Hello, we have several labs with MACs on our network. Just recently, the MACs started having issues authenticating to our Windows 2003 AD. They show a red dot at login which I believe means that the MAC isn't finding the login server. If we login locally, unbind and rebind it to the domain, the MACs seem to work fine for about a day. Then soon after the cylce starts all over again where the user can't authenticate and we have to unbind and rebind the MAC to the network.
We've looked at the logs on the domain controllers and we see no problems at all. I think this might have started to happen when the client starting moving the MAC computer accounts to different OU's in AD but I'm not positive.
The MAC version is 10.4.11
go to preferences --> date & time --> change the time server address to your logon domain controller
