Got a really odd problem that's only started to happen in the last 2 weeks, our domain controller freezes and locks all the clients up on the network. I can still ping it, but can't access any shares on it.
There's nothing at all in the error logs, I can't seem to track it down! Anyone seen anything like this before? The only way I can fix it is do a dirty power down and turn it back on.
Our DNS is set up OK and there's no physical network problems.
The server is a Dell Poweredge 1750 running Server 2003 Standard SP1, Dual Xeon 3.4 Ghz and 4GB RAM. It only serves as the domain controller and file server. DNS, DHCP etc are run on other machines.
