We are having troubles with setting up Outlook Anywhere (RPC over http) on SBS 2003.
Microsoft Remote Connectivity Analyzer reports an error when testing the NSPI-interface on Port 6004.
When trying to connect on port 6004 directly from the exchange server/ rpc proxy (single server scenario) the connect failes. Port 6001 and 6002 are able to connect with telnet.
The registry key ValidPorts under HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\Rpcproxy are correct. Windows Firewall is disabled.
What can be the reason for this issue?
Small Business Server 2003 Service Pack 2
Exchange 2003 Service Pack 2
