“553 Sorry, that domain isn’t in my list of allowed rcpthosts” “Relaying prohibited” error in MS OUTLOOK 2007

You get this error when the outgoing server (SMTP) does not recognize you as an authorized user. This can happen for various reasons but in general you’ll encounter this when you want to send a message through an SMTP server that is on another network than you are currently connected to.

Enable authentication for your SMTP server

When this happens, you can configure your outgoing server to use authentication before sending this message. To do this, you must first open your account settings;
• Outlook 2010
File ---Account Settings--Account Settings…
• Outlook 2007
Tools---Account Settings
• Outlook 2003 and 2002/XP
Tools----E-mail Accounts---button Next



Once you have opened the list of configured accounts;
Select your mail account--- button Change---button More Settings--tab Outgoing Server--- select: My outgoing server (SMTP) requires authentication

Note: Some ISPs have configured their SMTP servers to never allow sending messages from another network. In this case you can ask the administrator of the network you are connected to (in our example that would be the administrator of the hotel network) for their SMTP server settings or use the web mail provided by your ISP instead.

Find Detailed Hardware Information with Speccy

Want to know exactly what your computer is made of?  Speccy is a new free tool from the developers of CCleaner that gives you detailed information about your computer hardware.
Note: Speccy is currently a public beta, so if you’d rather not use beta software, wait to use it until it’s fully released. 
Speccy is available both in an exe installer and a portable version.  Choose the one that works best for your needs, and download.  The portable version is especially useful for checking hardware on others’ computers, such as one your considering purchasing at a store.  If you use the portable one, simply run it; otherwise, run the installer and set it up on your computer.
Get your hardware info
Once setup is out of the way, you can see all of your system’s hardware information.  Speccy needs to run in administrative mode, and brings up a UAC prompt by default.  If it doesn’t, you may see this warning.
sshot-1
It will still run the program, but will not have all the information.  Just exit the program and run it again in administrative mode.  To do this, right click on the program and select “Run as Administrator.”
sshot-26
Now you can see a detailed overview of all of your computer’s hardware.
sshot-22
You can view more detailed information by clicking each of the sections.  The CPU panel gives you advanced information about the technologies your processor supports, its code name and family, bus speeds, temperature, and more.
sshot-25
Clicking on one of the graph indicators shows you the temp or speed over time while Speccy was running.
sshot-27
It shows you the brand, part number, frequency, latency, and more, which is really great information to have if you’re considering upgrading or adding more RAM.
sshot-29
The motherboard page even tells you what chipset and BIOS you have.
sshot-30
Speccy gives you very detailed information about your hardware, and this can be very useful information when troubleshooting problems.  It lets you save a snapshot of your computer’s current hardware information so you can view your current information later, or could even send it to a support team so they could also see what is in your computer.
sshot-2010-02-17-[18-11-45]
Speccy will run on XP, Vista, 2000, 2003, and Windows 7 (32 & 64-bit versions). Remember once again, Speccy is still a beta program, so only use it now if you feel comfortable running unreleased programs.  Otherwise, wait and try it in a couple weeks, as Priform says it should be finished at that time.

What is hiberfil.sys and How Do I Delete It?

You're no doubt reading this article because there's a gigantic hiberfil.sys file sitting in the root of your drive, and you want to get rid of it to free up some space... but you can't!
Luckily, you actually can delete it, and today we'll show you how.
image
The more memory you have in your PC, the bigger the file will be.
So What is hiberfil.sys Anyway?
Windows has two power management modes that you can choose from: one is Sleep Mode, which keeps the PC running in a low power state so you can almost instantly get back to what you were working on. The other is Hibernate mode, which completely writes the memory out to the hard drive, and then powers the PC down entirely, so you can even take the battery out, put it back in, start back up, and be right back where you were.
Hibernate mode uses the hiberfil.sys file to store the the current state (memory) of the PC, and since it's managed by Windows, you can't delete the file.
image
So if you never use it, and want to disable Hibernate mode, keep reading. Personally I stick with Sleep Mode the vast majority of the time, but I do use Hibernate quite often.
Disable Hibernate (and Delete hiberfil.sys) in Windows 7 or Vista
You'll need to open an administrator mode command prompt by right-clicking on the command prompt in the start menu, and then choosing Run as Administrator. Once you're there, type in the following command:
powercfg -h off

You should immediately notice that the Hibernate option is gone from the Shut down menu.
image
You'll also notice that the file is magically gone!
image

Disabling Hibernate Mode in Windows XP
It's a lot easier in Windows XP to get rid of Hibernate mode.Just head into Control Panel –> Power Options, and then find the Hibernate tab.
1
Uncheck the box, reboot your PC, and then you can delete the hiberfil.sys file.

Audio Standards: AC'97 and HD Audio
The integrated audio solution included on Intel® Desktop Boards is either AC'97 or Intel® High Definition (HD) Audio.
AC'97
AC'97 (short for Audio Codec '97) is the audio codec standard developed by the Intel Architecture Labs in 1997. It is used mainly in motherboards, modems, sound cards and chassis front panel audio solutions. AC'97 supports 96 kHz in 20-bit stereo resolution and 48 kHz in 20-bit stereo for multichannel recording and playback. In 2004, AC'97 was superseded by Intel® High Definition Audio (HD Audio).
HD Audio
Intel® High Definition Audio refers to the specification released by Intel in 2004 for delivering high-definition audio that is capable of playing back more channels at higher quality than previous integrated audio Codecs like AC'97. Hardware based on HD Audio is capable of delivering 192 kHz/32 bit quality for two and 96 kHz/32
bit for up to eight channels.

Microsoft* Windows Vista supports High Definition audio peripherals only (such as front panel audio solutions).

How to Identify your Desktop Board Audio Codec

The Technical Product Specification (TPS) for each Intel® Desktop Board will indicate whether your board supports AC’97 or HD Audio. To find the TPS for your board:
  1. Go to http://support.intel.com/support/motherboards/desktop/
  2. Select your desktop board.
  3. Click Product Documentation in the left-hand navigation channel.
  4. Select Technical Product Specification.
Refer to Front Panel Audio Header Pinouts for additional onboard header pinout information.
How to Identify your Front Panel Audio Solution Codec
To identify your front panel audio solution’s audio codec, refer to the specifications or documentation for your PC chassis or front panel module. Note that AC’97 and HD Audio front panel solutions are different and may
not be directly compatible or interchangeable.
You can also physically check the audio cable of the front panel audio solution. If there is a cable connected to Pin 4, you have an HD Audio module; if there is no cable to Pin 4, you have an AC97 module.




Audio Control Software
Audio settings are controlled by audio control software, installed along with the audio drivers for your desktop board. Depending on your Intel Desktop Board model, one of the following applications will be installed:
  • IDT* Audio Control Panel
  • Realtek* AC’97 Audio Control Panel
  • Soundmax* Audio Control Panel
Each of these software applications allows you to perform basic audio configurations such as volume control, audio port configuration, jack sensing and speaker tests. Advanced features can vary.

CD-IN Connector No Longer Required
Some Intel® Desktop Boards do not include an onboard ATAPI CD-ROM connector. These boards include a digital audio solution which does not require an additional cable connection between the CD-ROM drive and the onboard ATAPI CD-ROM connector. See On board CD-ROM Connector No Longer Required for additional information.

Using S/PDIF (Optical)
S/PDIF (Sony*/Philips* Digital Interface) is an audio transfer format interface that allows the transfer of digital audio signals from one device to another without having to be converted first to an analog format signal, which can degrade audio quality.
The most common connector used with an S/PDIF interface is the RCA connector, the same type that is used in consumer audio products. An optical connector is also sometimes used. If you connect directly to your speakers, they must support S/PDIF input.
Intel® Desktop Boards may include either S/PDIF connectors on the back panel or an S/PDIF on board header. If your desktop board does not include any S/PDIF capabilities, you can disable onboard audio and install a soundcard that includes it.
For Intel® Desktop Boards that include S/PDIF to the back panel
The image below shows the two different S/PDIF connectors on the back panel of a desktop board and indicates the type of cable you’ll need for each.

For Intel® Desktop Boards that include an S/PDIF onboard header
Refer to the following table for the pinout of the 3-pin onboard S/PDIF header.
Pin Description
1 Vcc
2 S/PDIF out
3 Ground



Configuring 2-Channel Audio
The line out connector, located on the back panel, is designed to power either headphones or amplified speakers only. Poor audio quality may occur if passive (non-amplified) speakers are connected to this output.
To view a short demonstration video on configuring multi-channel audio, click Audio Setup Video Demo.



Configuring 6-Channel Audio
Installing the audio driver from the Intel® Express Installer CD-ROM enables the flexible, analog audio system. The back panel audio connectors support up to six speakers and are retaskable using the audio driver interface.

Jack retasking is a feature that allows an audio jack to support more than one function. For example, the pink audio jack can support microphone input when the system configuration is set to Stereo Mode, and as Center/LFE or Rear Surround (depending on the audio solution used) when set as 6 channel.
Item Description
A Line In [retaskable as Rear Left/Right Out]
B Line Out [Front Left/Right Out]
C Mic In [retaskable as Center/LFE (Subwoofer) Out]
Connect speakers as follows:
  • If using two speakers, connect the pair to connector (B).
  • If using four speakers:
    • Connect the front left/right speakers to connector (B).
    • Connect the rear left/right speakers to connector (A).
    • Using the audio driver interface, retask connector (A) to be Rear Left/Right Out.
  • If using six speakers:
    • Connect the front left/right speakers to connector (B).
    • Connect the rear left/right speakers to connector (A).
    • Connect the center/subwoofer speakers to connector (C).
    • Using the audio driver interface, retask connector (A) to be Rear Left/Right Out and retask connector (C) to be Center/LFE Out.
To view a short demonstration video on configuring multi-channel audio, click Audio Setup Video Demo.


Configuring 8-Channel Audio
8-channel audio is available only on certain Intel Desktop Boards.
After installing the audio driver from the Intel Express Installer CD-ROM, multi-channel audio can be enabled:
  • Connect speakers to A, B, C, D, or E as shown in the figure below, up to eight speakers.
  • Two types of S/PDIF connectors are available: coaxial (G) and optical (F). Select the proper connector according to the style of S/PDIF speakers that will be used.
  • The back panel may look like either of the following, depending on board model.
Item Description
A Rear left/right out (multi-channel audio)
B Line in
C Line out (2-channel) or front left/right out (multi-channel)
D Mic in (re-task for multi-channel)
E Center/Low Frequency Effects (LFE) out (multi-channel)
F Optical S/PDIF (Toslink) line out
G Optical S/PDIF (RCA) line out

To view a short demonstration video on configuring multi-channel audio, click Audio Setup Video Demo.


Configuring Front Panel Audio
If your desktop board includes a front panel audio header, you can add a front panel audio module that allows for Line In and Line Out functionality. Check the Technical Specifications for your board to see if it includes an onboard front panel audio header.
Refer to the Product Guide for information on connecting a front panel audio module. The product guide is available either:
  1. On the Intel Express Installer CD that came with your desktop board.
  2. As a PDF file on the support Web site for your board. Go to Desktop Boards Home, select your desktop board and then choose Product Documentation to find the Product Guide.
If you are connecting front panel audio directly to a chassis with built-in front panel audio connections, refer to the documentation that comes with the chassis for the appropriate cabling details.
After connecting a front panel audio solution, you can test front and back panel audio functions within the audio software you have installed. Depending on the capabilities of your system’s audio solution (drivers and software), you may be able to:
  • Mute the back panel audio when front panel audio is active.
  • Have both back and front audio active simultaneously (for example, speakers connected to the back and headphones connected to the front).
  • Designate whether you are using headphones, 2-speaker systems, 4-speaker system, etc.
Installing Add-In Audio Cards
If you want to install a 3rd party add-in audio card instead of using the onboard audio, follow these steps:
  1. Disable onboard audio:
    1. Press F2 during boot to enter BIOS Setup.
    2. Go to the Advanced > Peripherals Configuration menu.
    3. Disable Onboard Audio.
    4. Save by pressing F10 and exit the BIOS Setup.
  2. Install the 3rd party add-in audio card, as per the installation instructions that come with the card.

32-Bit Playback and Recording
None of Intel's desktop boards support 32-bit audio playback or recording. The highest sampling resolution available is 24-bit. This is deemed to be sufficient because popular digital formats like Dolby* and DTS* only support sampling resolutions of 16-bit to 24-bit. High-end external audio card also support up to 24-bit sampling resolution only.

Enabling Multistreaming PlaybackMultistreaming allows you to listen to two different audio sources on two different speaker sets. For example, you can listen to one audio source through the back panel speakers and a second audio source through front panel headphones or speakers.
Check the Audio Subsystem section of the Product Guide or Technical Product Specification (TPS) to see if your Intel® Desktop Board supports multistreaming.
The following documents provide examples of how to set up multistreaming playback.

  5. Install all of rest of the latest drivers for your board, EXCEPT the audio driver.
  6. Re-enable audio in BIOS:
    • During boot, enter the BIOS setup by pressing F2.
    • Enable audio on the Advanced > Peripheral Configuration menu.
    • Press F10 to Save and Exit.
  7. Restart the system and cancel any “new hardware found” messages.
  8. Install the latest audio driver.
  9. Restart the system.

Some Speakers Don’t Play

If you can hear sound coming from some speakers, but not others, check the following:
The system may assume you are using two-channel (stereo) sound, even if you have plugged in four or more speakers. Select the correct speaker type with the Windows Speaker icon or the third-party sound mixer you’ve installed.
  • The speakers may be connected to the wrong jacks. Make sure you connect all speakers to the correct jacks. If you connect them to line-in or microphone jacks, they won't work. Refer to the documentation that came with your speaker system for connection details.
  • The balance settings may be incorrect. If you hear audio from the left speakers only or the right speakers only, check the balance. Balance control needs to be centered with the Windows Speaker icon or a third-party sound mixer.
  • Some 4.1 speaker systems (one subwoofer and four satellite speakers) are designed to connect to computer gaming sound cards. If you connect to a standard computer sound card (or onboard audio) instead, look for an input switch and make sure it is set to ‘stereo’. Consult the documentation for your 4.1 speaker system for more details.
  • It is common to hear only front right and front left channels from a multichannel receiver when it is connected to S/PDIF. If your receiver has discrete multichannel analog connections, it is recommended that they be connected to the Analog Front-Out, Rear-Out, and Center/Subwoofer Out. See Creative Labs' Knowledgebase* for additional information.
On some systems with integrated audio, audio jacks have multiple uses. For example, in six-channel mode on some systems, the normal line-in and microphone jacks might be reconfigured to work with rear and center/subwoofer speakers. In such cases, the mixer controls need to be reset.

No Sound Output to Speakers or Headphones
No sound output can be caused by several problems. The following suggestions may resolve the problem of no audio output:
Onboard audio is disabled in the BIOS
The BIOS Setup program is accessed by pressing the key after the Power-On Self-Test (POST) memory test begins and before the operating system boot begins. Go to the Advanced > Peripheral Configuration menu to make sure onboard audio is enabled.
Audio settings in the sound mixer are incorrect
Check your audio mixer software to ensure audio is not muted or the volume level is not turned too low.
The speakers or headphones may be connected to the wrong jacks
Make sure you connect all speakers to the correct jacks. If you connect them to line-in or microphone jacks, they won't work.
Audio drivers are not properly installed
Check Device Manager under the Sound, video and game controllers section for any errors associated with the audio driver. Reinstall the audio driver if necessary.
Audio to back panel is muted if front panel is connected
Check your audio mixer software for a setting that mutes back panel audio if you have plugged headphones into a front panel audio solution. Uncheck this setting to allow audio to both the back and front.
Sound Playback is set to wrong device
In Control Panel > Sounds and Audio Devices, go to the Audio tab. Check the default device for sound playback; there may be multiple selections. Select the desired device, either rear panel or front panel.

Sound is Distorted or Scratchy
Distorted or scratchy sound can be caused by several problems. Improving the sound can be as simple as rearranging your hardware components. The following suggestions may resolve the problem of scratchy sound:
  • Are there any other devices around the speakers or wires for the speakers? Electro-magnetic interference can cause poor audio. Try moving your speakers and wires around and away from other devices.
  • Have you recently added any new cards to your computer? Cards within the computer can also cause electro-magnetic interference. Try moving the card to another location within the computer, if possible.
  • Verify that you are not encountering a hardware issue with the speakers you have by trying another pair of computer speakers.
  • Poor audio quality or low volumes may occur if you are using passive (non-amplified) speakers.
  • Are your speakers too close to your monitor? The speakers can pick up electrical noise from your monitor so move them farther away. Subwoofers should never be placed near the monitor because their powerful magnets can interfere with the picture. They should be on the floor to maximize low-frequency transmission.
  • Are you experiencing sound problems only with particular games or programs? If you notice sound problems such as stuttering voices and static on some games or programs but not others, check with the software vendor for a software patch.
Microphone Does Not Work
If you are experiencing problems when recording audio from a microphone plugged into the rear microphone port:
1. Update to the latest audio driver for your desktop board from Intel’s Download Center.
2. Ensure you’ve selected the rear panel microphone jack as the default record device:
a. Click Start > Control Panel > Sound and Audio Devices.
b. Go to the Audio tab.
c. Set the Sound Recording Default Device to the rear input.
d. Click OK.

AC'97 Front Panel Audio Does Not Work with Onboard HD AudioThe onboard front panel audio connector provides microphone in and line out signals for the front panel. Many chassis manufacturers offer chassis with front panel audio ports and cabling. Those front panel solutions may support either AC’97 audio or High Definition (HD) audio.
The onboard audio headers on Intel Desktop Boards with the Intel® 945 chipset and later support HD audio.
Compatibility:
  • HD front panel audio solutions should be plugged into HD onboard headers.
  • AC’97 front panel audio solutions should be plugged into AC’97 onboard headers.
  • Some AC’97 front panel audio solutions (but not all) may work with HD onboard headers.
If you want connect an AC’97 front panel audio system to HD onboard headers, try these steps:
  1. Connect Mic_IN (MIC) to MIC2_L.
  2. Connect Audio_R (RIN) to OUT2_R
  3. Connect Audio_L (LIN) to OUT2_L.
  4. MIC_RET and OUT_RET are for HD audio only; you don't need to connect them for AC'97 audio.
Intel does not validate AC’97 front panel audio solutions with boards using HD audio. If the steps above do not work, you will need to use an HD front panel audio solution for full compatibility with Intel Desktop Boards using Intel 945 chipsets and later.
Audio does not work with Windows Vista Service Pack 1After you install Windows Vista Service Pack 1 (SP1), you may experience one or more of the following problems with sound:
  • No sound is produced when you play audio files or run programs that have an audio component.
  • The speaker symbol next to the clock in the notification area may display the following message: No Audio Output Device is installed
  • The Sound Controller in Device Manager displays a yellow exclamation point.

The Svchost.exe file is located in the %SystemRoot%\System32 folder. At startup, Svchost.exe checks the services part of the registry to construct a list of services that it must load. Multiple instances of Svchost.exe can run at the same time. Each Svchost.exe session can contain a grouping of services. Therefore, separate services can run, depending on how and where Svchost.exe is started. This grouping of services allows for better control and easier debugging. 

Svchost.exe groups are identified in the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Svchost
Each value under this key represents a separate Svchost group and appears as a separate instance when you are viewing active processes. Each value is a REG_MULTI_SZ value and contains the services that run under that Svchost group. Each Svchost group can contain one or more service names that are extracted from the following registry key, whose Parameters key contains a ServiceDLL value:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Service
To view the list of services that are running in Svchost:
  1. Click Start on the Windows taskbar, and then click Run.
  2. In the Open box, type CMD, and then press ENTER.
  3. Type Tasklist /SVC, and then press ENTER.
Tasklist displays a list of active processes. The /SVC switch shows the list of active services in each process. For more information about a process, type the following command, and then press ENTER:
Tasklist /FI "PID eq processID" (with the quotation marks)
The following example of Tasklist output shows two instances of Svchost.exe that are running.
Image Name         PID      Services
========================================================================
System Process 0 N/A
System 8 N/A

Microsoft Download Manager Available for Free Download

The Microsoft Download Manager enables you to download files from the Internet in a more reliable and faster way than using a browser alone. Using the Download Manager makes it easier to download large files such as an application or multimedia files. Also, it has resume support so that you can continue downloading files from where it left off the last time.
I tested it with a couple of sites and I managed to get very good download speeds using Microsoft Download Manager, than using IE.
  
Tip: Increasing the maximum number of connections improves the download speed.
By default it’s set to "Use browser settings", which caused the following error when downloading a file. I had to enable the No proxy option to make the download work.
Overall it’s a nice little download manager, and it would be great if future builds include browser integration (with IE, at least) support.
