I have Exchange Server 2007 installed on Windows Server 2003 x64 R2. Windows Server is NOT a DC so when I put it on the domain, my group policy enabled the Windows Firewall on it. I think that it is blocking everyone from connecting to the server. Outlook clients report that exchange server is unavailable when connecting to the new server and my other exchange server, which is on a DC, gives me this error:
Process mmc.exe (PID=4900). An remote procedure call (RPC) request to the Microsoft Exchange Active Directory Topology service failed with error 1722 (Error 6ba from HrGetServersForRole). Make sure that the Remote Procedure Call (RPC) service is running. In addition, make sure that the network ports that are used by RPC are not blocked by a firewall.
Anyone know how to correct this?
