Operating system
Windows Server 2003
Problem
When we resume the computer from standby mode, the computer may stop responding. Sometimes it may also see the "Applying Personal Settings" message box for up to an hour before the desktop appears.
Typically, when you resume a Windows Server 2003-based computer from standby, the computer is locked. Therefore, you must log on to the computer before you can access the desktop. However, when this problem occurs, the computer is not locked, and the Windows Server 2003 logon screen does not appear.
Solution

When we turn on user environment (Userenv) logging, domain Distributed File System (DFS) services may not work after the computer resumes from standby. Additionally, you may receive messages that resemble the following messages in the %SystemRoot%\Debug\UserMode\Userenv.log file.
According to Microsoft this problem may occur if the Winlogon process tries to process group policies before other components are running. However, there are several other scenarios that may cause this problem. Make sure that the following components are started and that they are configured correctly Netlogon and DFS services are started.
  • Domain controllers have the read and apply rights to the Domain Controllers Policy.
  • NTFS file system permissions and share permissions are set correctly on the Sysvol share.
  • DNS entries are correct for the domain controllers.
