I have been working with the IPS systems within my corporate

these connections and is blocking them by considering them port

Placing a packet capture on the network and server did no good as
the workstations blocked them and the workstations that didn't block
the connections would only reply with a reset flag.

These connections happen at the most sporadic times ranging anywhere
throughout the day or night. We would like to put a program on the
server that will monitor for executables and what port they run on
or open up. This program must be able to log the instances and be
able to filter what ports are being monitored. Does anyone know of
any software programs that will run on Server 2008 and have the
above stated capabilities?

I'd give MSofts Port Reporter and its Parser a try:
The Port Reporter tool logs TCP and UDP port activity. The tool is a
small program that runs as a service on a computer that is running
Windows Server 2003, Windows XP, or Windows 2000.

On Windows Server 2003 and on Windows XP-based computers, the service
can log the following information:
a.. The ports that are used
b.. The processes that use the port
c.. Whether a process is a service
d.. The modules that a process loaded
e.. The user accounts that run a process


I second Port Reporter. However, if the OP wants something that doesn't
require installation and can be run interactively , Process Monitor [1]
might be another option.

One could also use Wireshark [2] or Network Monitor [3] to analyze the
packets. Or at least hook something like netcat [4] to port 88/tcp on some
clients and see what the server actually tries to send (of course the
clients will respond with TCP-RST if there's not listening socket on
that port).
