Hello,
After making some changes to group policy security (disabling both SMB signing and do not store LM hash value) my XP workstations can still sign on to the domain and have file sharing between workstations, but have no access to the server. My Windows 7 machines are experiencing no problems at all. This problem persists even after changing GP settings back to their original values and rebooting the server. I have tried resetting the account on one of the workstations, resulting in no access to the domain at all. This is driving me nuts....HELP! Thanks
