I have 2 domain controllers and 1 exchange server running (all Win2k). DC#1 has the Global Catalog, running DNS and DHCP. DC#2 doesn't have the Global Catalog but is also running DNS. All servers/workstations know of the primary and secondary DNS. DC#1 has been going down periodically (hardware issues still working on). In the meantime, users can still get on the Internet but Outlook/Exchange doesn't work. The Exchange server has both DNS server entries. Am I missing something? Do I need to move the global catalog over to the backup domain controller for Exchange to work? I will probably just move the GC over to the other DC anyway - is it as easy as replicating and then checking "Global Catalog" in AD Sites and Serv? Thanks a ton!

You probably won't get many replies to this since you posted it in the NT Forum. :) Also there are no BDCs in 2K server. :) Life is more painless for those who are brainless.

Oh Gosh! My bad. Ignore that previous post about NT... LONG day. :) Life is more painless for those who are brainless.

The GC should be on both DCs for failover as well as dns on both. Give a person a fish, they eat for a day. Suggest they internet search and they learn a skill for a lifetime.
