Ports used by Exchange Server while communicating with MS Outlook Clients
We are running MS Exchange 2003 and using MS outlook clients that connect over RPC End point mapper (port 135) to Exchange Server. We wish to know which TCP port the exchange server uses in turn for further communication with the outlook clients.
Based on the monitoring tools, we just saw that it used tcp 1144 once but then it was changed to 1164.
The objective is to implement QoS on the routers based on the protocol type.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
For more information see http://support.microsoft.com/kb/832017 and browse down to the section on "Microsoft Exchange Server and Outlook clients." This also has a nice table of all the ports and services behind those ports.
If you set your QoS for ports 35, 443, 6001, 6002, and 6004 for your exchange server you should be fine.
Hope that helps,
