IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base:
256986 Description of the Microsoft Windows Registry
SUMMARY
The versions of Microsoft Windows listed at the beginning of this article include debug logging of the user profile and the Windows system policy processes. To turn on debug logging, modify the registry on the computer on which the logging occurs. The debug logging functionality is also available with Microsoft Windows NT 4.0, but the functionality requires a checked (debug) build of the Userenv.dll file on Windows NT 4.0.
For additional information, click the article number below to view the article in the Microsoft Knowledge Base:
154120 Debugging User Profiles and System Policies in Windows NT 4.0
You can use the output of this logging to troubleshoot problems with user profiles and Group Policy processing.
MORE INFORMATION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
Use Registry Editor to add the following registry value (or modify it, if the value already exists):
Key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
Value: UserEnvDebugLevel
Value Type: REG_DWORD
Value Data: 10002 (Hex)
UserEnvDebugLevel can have the following values:
NONE 0x00000000
NORMAL 0x00000001
VERBOSE 0x00000002
LOGFILE 0x00010000
DEBUGGER 0x00020000
The default value is NORMAL (0x00010000). NOTE: To disable logging, select NONE (where the value would be [0X0000000000000]).
You can also combine the values. For example, you can combine VERBOSE 0x00000002 and LOGFILE 0x00010000 to get 0x00010002. So if UserEnvDebugLevel is set with a value of 0x00010002, this turns on both LOGFILE and VERBOSE. Combining these values is the same as using an AND statement:
0x00010000 AND 0x00000002 = 0x00010002
The log file is written to the %SystemRoot%\Debug\UserMode\Userenv.log file.
Additional query words: userenv.log enable

Although you'll note they say the default value is normal (10000 hex) yet normal is defined as 1.
