Today is the first day back from our autumn break, when staff attempted to log in they were met "Windows cannot locate the server copy of your roaming profile and is attempting to log you on with your local profile. Changes to the profile will not be copied to the server when you logoff. You may receive this error message because of network problems or insufficient security rights. If this problem persists, contact your network administrator." Access Denied. It has affected all my users, I checked my firewall "as past issues resided there". The main thing I noticed was from a computer on my staff network the Kerberos 5 service was sent to the server on my student network. I presume that this is where the problem lies, but I am not sure where a change could have been made to force my staff users to attempt to authenticate on the student network. I have searched on line and found issues related to permissions but again most writings had to do with a single user not a subnet. Any advice would be greatly appreciated.
