I have gone through all the procedures of removing the first exchange server from our organization using article (). When we bring down the old server none of our users can access email. Outlook error says cannot contact exchange server or exchange server is unavailable. Also we get an error in ESM on the 2003 server that reads:
The RPC server is unavailable
ID no: C00706ba
Exchange system Manager
I have change the Recipient Update service to reflect the new server and have check all dns settings.
