Roaming profiles are not saved if you log off a Windows Vista-based, Windows XP-based, or Windows 2000-based computer

If you log off a Windows Vista-based, Windows XP-based, or Windows 2000-based computer, you experience the following symptoms:

• Roaming profiles are not saved to the profile server.
• Event entries are not added to the Application log.
• If you are using the Microsoft User Profile Hive Cleanup Service tool, the tool does not log the log-off process.
• The following messages are listed in the Userenv.log file:
  USERENV(1b0.7f0) 16:37:20:209 UnloadUserProfileP: Wait succeeded. In critical section.
  USERENV(1b0.7f0) 16:37:20:360 UnloadUserProfileP: Didn't unload user profile, Ref Count is 2

This issue may occur with certain versons of the NVIDIA video card driver. The NVIDIA driver loads the profile two times. When the user logs off, the first profile is unloaded. However, the other copy of the profile is still loaded.

To resolve this problem, use either of the following methods.
