Jamelia,

Since SP1 you don't need to enter the 593 or even the GC at all. The
validports key is entered automatically anyway every 15 minutes.

However, I have another problem.
We migrated from a Windows 2000 - Exchange 2000 FE/BE configuration to
Windows 2003 - Exchange 2003. Went like a charm.
Now we want to use the RPC over HTTP so I made sure we were on
Exchange 2003 SP1 for both machines. I set my BE server to be BE for
RPC over HTTP. I set my FE server to be FE for RPC over HTTP.
My OWA is working normally. Certificate is ok.
* https://publicname/rpc is returning the expected result.
* rpcping to the RPC Proxy server (with the -E switch) returns 200
(OK)
* rpcping to the BE server (ex. with -e 6001) returns nothing. It is
just waiting. Which is the same we experience when trying to connect
through outlook. In the connections status windows the status remains
on 'connecting' but nothing happens.
* netstat -a on the BE server shows ports 6001, 6002 and 6004
listening.
* The FE is located in the DMZ but the FW shows no dropped packets.
* Before migrating our production systems, I did setup a test
environment, where I went through the complete migration +
configuration of RPC/HTTPs, without having encountered this problem.

Is there anyway to further troubleshoot this problem ?
Any help would be greatly appreciated.

Toon.
