We just noticed when applying patches to our domain controllers (2 Win2003), that when one was down, no athentication was possible on the network. Then, when the other was down, the same thing happened. Only when both are running, is authenticastion possible.

This, of course defeats the purpose of redundant dcs. We are currently investigate a possible DNS problem, but haven't come up with a solution.

And yes, we've checked to make sure each box was running AD, GC and DNS.

Any ideas would be helpful.

entries on your dhcp scope to the ip of each domain controller as the primary and secondary.

Thanks for the reply. I checked our DHCP server and the DNS Server option is set to the IP of both domain controllers. However, we only have one DHCP server. I'm thinking we should have DHCP server running on both controllers? Am I right...I will investigate further.
