1) Windows 2003 server / AD
2) Windows 7 laptop
Upon logon, the logon script gave a warning about F: drive letter error (collision between DVD drive and mapped drive). Tried moving the DVD drive to another drive letter (available, not mapped).
Then - the logon freezes with a black screen + mouse cursor. When moving the DVD back to F:, windows logon completes with the error mentioned above.
If the user tries to log onto the domain using another computer (even other W7 computers) - the problem does not occur - so this seems to be an issue on the laptop (HP Probook, tried with a complete system recovery).
Any ideas what might be causing this?
