Turns out that you’re right. The
end-point mapper selected this port to communicate on. FYI – once Exchange is rebooted or
failed over the port can and probably will change (to anything over 1024 as
stated below). Looked very odd to me that it picked such
a high ambiguous port – but hey – what do I know! Thanks for all your responses! Joe

[mailto:[EMAIL PROTECTED] Sounds like this is the port that Exchange
has chosen for RPC traffic with the Outlook clients. Unless you make a registry
change on the server, Exchange will pick ports above 1024 (more or less
randomly) for RPC with clients. http://support.microsoft.com/kb/155831 has
a passing mention of this. Hunter From:

doesn’t appear that we have a static port assigned though. Joe

[mailto:[EMAIL PROTECTED] Could be that you have a statically mapped
port assignment for a particular service (NSPI Proxy, IS, SRS, etc.).
Check out the following article. You can the look for the

[EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Pelle, Joe Hello! When I do a netstat
–an on my Exchange 2003 server I see a lot of connections on
TCP 18053. All of our email clients connect to this Exchange server and
just about all of them appear to have a connection via this port. No one
seems to have any idea what that traffic could be… Does anyone have any ideas? Any help or insight is greatly appreciated! Joe
