This problem just seemed to start for no real reason. Here are the event ids that I'm getting:
process MAD.EXE (PID=2244). Topology discovery failed, error 0x80040a02.
process MAD.EXE (PID=2244). All Domain Controller services in use are not responding: myserver.dcmyserver.local
windows cannot determin the user or computer name. (the rpc server is unavailable.) group policy processing aborted.
prosess EMSMTA.EXE (PID=2968). topology discovery failed, error 0x80040a02
its a dell poweredge running windows exchange server 2003 r2.
here is what i dont get. anyone that is using a pc on the network outlook works fine. send and recieve and connections are fine. however, anyone using a mac has their connections lost to the mail server. sometimes system manager opens on the server, other times it does not. restarting the server clears this up, but only for a short time and it all starts again. could there be a hardware issue with the network cards? or is this something else? when i read the microsoft explaination about this it doesnt seem to fit my problem as only mac users are the ones having problems.
these are the other that seem to start the entire process of connection lost with mac users:
prosess STORE.EXE (PID=2992). Topplogy discovery failed, error 0x80040a2.
EXCHANGEAPPLICATIONPOOL (PID=4720). Topology discovery failed, error 0x80040a02
any help would be great!
