We have a 2008 Terminal Server connected to a Windows black box on the network. The TS has a group policy applied to it that maps drives (Group Policy Preference in computer section) at logon. The drive mapping to the Windows server has the username and password stored.
When the user logs in, the drive is not mapped and trying to open it prompts the user with a dialog saying "Logon failure: unknown username or bad password." which has the correct username already displayed.
If I enter the password now(same on as stored in the GPO), the drive maps correctly and I can see the contents of the folder.
If I log off and log back on again, the same thing happens. Clicking 'Remember my credentials" does not fix this problem.
Has anyone encountered this problem before? Any help solving this will be much appreciated.
