Have you tried using a utility like Active Ports
(http://www.ntutility.com) or TCPview (www.sysinternals.com) to check
what ports are being opened on your box, and by what process?

Also, you can sniff the network traffic and see what types of packets
are being sent out.

Subject: exchange server attempting to connect to odd ports

Just rebuilt our exchange box and I see it trying to open connections to
the following udp ports:

1140
3069

This is happening to a 192.168 IP address so it's not getting far but I
find it curious.  Happens every minute or so.  Have scanned for spyware
and run AV software on the box and both have come up empty.  Any other
ideas?  Thanks.

 Matt
