Having an issue with a new 2008 Server Standard installation. Domain controller. Added the server to the existing domain successfully and it is working fine for the most part. Users can access the file share just fine. DNS and Active Directory appear to be happy.
The problem is when attempting to change security permissions of a shared folder (add/remove users) on the server, I'm prompted with a user-name and password box with the instructions "Enter the name and password of an account with permissions for "server-name". I'm already logged in as domain\administrator. There is also a log generated with error4625 with a Null SID. It seems like the computer is not allowing the domain\administrator account permission to make changes. I can however browse the network from another DC and make changes to the share security from there (as domain\administrator). Another clue is that on the problem server if I browse the network to itself and then try to open the share folders I get the same user-name and password prompt. I can however see the share and access the share from any other server or workstation on the network. We installed two of these servers, the other one is fine.
I'm thinking I may dis-join and rejoin the computer to the Domain. What do you guys think? Let me know if yo need further details. Thanks!
