I hope you are using a corrent User Profile Path:
Used to enter a network path when enabling a roaming or mandatory user profile for a selected user.
The path you enter follows the form: \\server name\profiles folder name\user name. For example,\\puma\profiles\jeffho.
When assigning a mandatory user profile, open System in Control Panel to the User Profiles tab and copy a preconfigured user profile to the user profile path location. Then, rename the NTUser.dat file in the user profile as NTUser.man.
Remember that you need to create a share on the appropriate server, grant Full Control to Everyone, and type the full path in User Profile Path, such as:
\\airedale\profiles\cristalw
If you did do this and the problem is still occuring then check that the profile is actually being created. If it is not being created than re-install the latest service pack.
Good luck.
