I am trying to setup RPC over HTTP on my Exchange 2003 (single server setup)
I have followed the instructions from http://www.petri.co.il/how-can-i-configure-rpc-over-https-on-exchange-2003-single-server-scenario.htm
When I run the test https://www.testexchangeconnectivity.com
I get to the point when it tries to ping 6001 Attempting to ping RPC endpoint 6001 (Exchange Information Store) on server exchange01.contoso.local.
The attempt to ping the endpoint failed.
I allowed for port 6001-6002, 6004 to route the traffic to my exchange server.
