    go into document and setting and click on the folder of that user. Delete ntuser.dat and then have that user re-login into the computer. This will create a new ntuser.dat

    NTUSER.DAT is essentially the HKEY_CURRENT_USER section of the registry for the user in question, I dont know that its possible to edite it (I suppose you could edit the registry and then export the relevant section but it would be messy and I would not recommend it).

    I'm not sure that this is causing the problem in any case, check the startup folder and and/or use Autoruns from sysinternals to determine what is the real issue.

    This file is the users registry hive.
    If you delete it they will lose any user specific settings which are stored in the registry. (under hkey/current user/[sid])
    When you login this file (located under c:\documents and settings\[username]\ntuser.dat) is loaded by the operating system and merged into the registry. If the file is corrupted you may have some problems logging in. Thenone's answere above may get you out of troulble, but there will be data loss.
