We have a windows domain with Win2k and Win2k3 servers. Everything has been working great except for one of server. It is a Win2k server with Exchange 2003. It is a domain controller. It has been working fine till yesterday.
We can connect to Exchange server and printers are fine but we cannot connect to Shared Folders. When you goto the server you can see the shares, but when you try to connect to them it brings up a login prompt. It has never done that before. None of the logins work, including Administrator account. Once you click Ok it just brings the Login prompt back up again. If you try to connect from a 2k3 server it says access denied.
Nothing has changed on the server so I am not sure what happened. Can anyone help?
