When using User Profile Management (UPM), sometimes 2 (two) user profile folders are created at logon. These user profile folders are used simultaneously during the session. This article explains how to fix this issue.
When a user logs on a computer managed by UPM, duplicate user profile folders Username and Username.domain are created in Documents and Settings folder. These two folders are created at the same time (see screen shot). They are locked and used by the operating system simultaneously.
Caution! Refer to the Disclaimer at the end of this article before using Registry Editor.
In order to fix these values, you must either recreate the damaged profiles or reset the wrong User Shell Folders paths. This can be performed:
Manually
By applying a custom Group Policy which resets User Shell Folders
Using a script that modifies the registry keys values
Or alternatively by using this Microsoft Fix-It tool: http://support.microsoft.com/kb/886549.
This issue can be caused by misconfigured User Shell Folders values in Windows Registry Database. Under HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders, every user shell folder path has to use %USERPROFILE% environment variable instead of “C:\Documents and settings\USERNAME”.
