We just installed a new Exchange 2003 server and we keep getting the error MSExchangeSA Event ID:9074 in the event log. Which results in email not working. It is the only exchange server on the network, and we also have a 2003 domain controller.
The server worked fine for the first two days it was online, then today we started having problems. The exchange server also says that it can't communicate with the domain controller. If I reboot the server for a short time email will work, then we start getting these errors. The 2003 domain controller has been online for 3 months and no user has had any trouble logging onto the domain.
