We upgrade all of our client machines on our school network to Windows 7 Pro. The Server runs Windows Server 2003 and there have been no changes to its configuration. When trying to logon as one of the students or staff I get the error message "You cannot log on because the logon method you are using is not allowed on this computer. Please see you network administrator for more details." I have tried the following -
"1. Run gpedit.msc.
2. Expand Windows Settings\Security Settings\Local Policies
3. Click on User Rights Assignment
4. Ensure that "Allow log on locally" includes Administrators, Backup
Operators, Domain Users or Users."
Unfortunately the buttons to make any changes are not active. Plus, all of these groups are already included. I also checked the "Deny log on locally" settings and have the same issue - non-active buttons. Also, there is nothing in that group anyway.
I am logged on as administrator when trying to make changes.
Please help. School starts next Monday.
