We are running Exchange Server 2003, for the last couple weeks every few days we will have several people complain that they cant connect to their E-mail.

When We remote into the Exchange server we get a message stating “The system cannot log you on due to the following error: The RPC server is unavailable” when trying to login to the network. Logging into it using the local admin account works fine though.

The only way we've been able to get everyone to reconnect properly is to reboot the server.

When checking the Event Logs there is no error/warning messages that seem to indicate what might be causing this.

Thanks

Yes the RPC service is up and running on the DC's, and the corresponding service on the exchange server also shows as started, and wont let me restart or stop it without rebooting the server.

Are you using the original admin credentials? (used to install the OS)

OK - I would start by looking at the following: http://support.microsoft.com/kb/555839

What third party services do you have running?

Does your DC has teamed NICs?

Are you running VMWare?

IS DNS properly configured on the DC? (Is it testing clean with DCDIAG /test:dns?)
