After installing SP1 on WIN7 64 bit I have lost all user permissons to my mapped share folders and files. The drives maps okay from the login script batch file (N:) I see N: but is has a red X under My Computer I can access the N: and see folders and files I can not open files or folders " access denied" No access to security tab on files or folders I can not dissconnect the map drive either (N:) "access denied" I do have admins right on the domain as well as the local machine. I did have acces to these directories prior to installing SP1. The drive we are mapping (N:) is to a 64 bit WIN2008 server running SP2. The DC is a 2003 32bit server, standard edition running service SP2. Thanks in advance for any help.
