We have Domain Controllers at our remote sites. Whenever our WAN link goes down, remote employees are unable to authenticate with their local domain controller to login/gain access to anything. It is as though they always use our PDC that is located in a different location. When the WAN link goes down - the authentication and access should still all go through the Remote DC, but it is not - and the remote employees are unable to access the local DC or login to their machines.
The WAN link is currently down and I was wondering if anyone had any recommendations on how to troubleshoot this issues? This is the perfect time to troubleshoot this issue. I am able to call the remote employees and have them try some things to get to the bottom of this.
We are on Server 2003 R2 and Domain Funtional Level of 2003.
Any ideas would be greatly appreciated!
