So now that I have that Strange problem with my messages sorted out, I would like to get back to my problem. We had a DC fail on the weekend. I know about it, but thought that it could wait till Monday morning as its one of three DCs in our net. (all W2K net.) However no such luck. It the OWA of E2K SP2 stopped working shortly after the DC fail, and after a restart of the E2K machine, there was a system attendant error message, all the following Exchange services failed too, (the Mail storage for example.) The DC that failed was the first DC I set up in our Domain, but all the Active Directory services that only run once in a domain, have been moved to a second newer DC. (Or so I thought). Does anyone have an Idea how this could be? The best thing is that the E2K server is also a DC, and It still wanted another DC... I got the original DC up and running again, and everything is fine, but I can't believe that I need only one old DC fail to virtually bring down my whole net. Any Ideas??
