256986 Description of the Microsoft Windows Registry


The checked version of Userenv.dll, in conjunction with a registry entry, creates a log file useful in troubleshooting and debugging problems with roaming profiles and system policies on Microsoft Windows NT version 4.0 clients.


To enable the log file:

  1. Rename the Userenv.dll file in the %Windir%\System32 directory to Usernv.orig or the unique name of your choice.
  2. Copy the checked version of Userenv.dll to the %Windir%\System32 directory of the client computer that you want to debug. The checked version of the Userenv file must match the version of the operating system being used.

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.

  1. Start Regedt32 and locate the following path:


  2. Create a new value called UserEnvDebugLevel as a reg_dword. Assign the value 10002 in hexadecimal format.
  3. Restart the computer with the .dll and registry changes in place.

For Microsoft Windows NT Server version 4.0 and Microsoft Windows NT Server version 4.0 Terminal Server Edition SP4 and earlier, log information will be recorded in c:\userenv.log and can be viewed with Notepad, WordPad, or the text editor of your choice. For Microsoft Windows NT Server version 4.0 Terminal Server Edition SP5 and SP6, log information will be recorded in %systemroot%\system32\userenv.log. Information displayed in the log includes: Profile Path, Profile Type, System Policy Path (useful to determine which server the Ntconfig.pol file was pulled from), whether the profile was successfully loaded and unloaded at the client, and if the remote profile is newer than the local profile.

A sample Userenv.log based on the following information is shown below.

   Username = profile
   Profile path defined in User Manager =
   Domain Controller = PDCServerName
   System Policy Path: PDCServerName\Netlogon

NOTE: The response to the seventeenth line.

   Profile is not reachable, error = 2

A check is made for the existence of a mandatory profile path being defined in User Manager for Domains (Servername\Sharename\ Mandatory profiles were not used in this example, so the test fails.
