Hello All,

I have been working with the IPS systems within my corporate workplace and we have noticed some strange activity where a virtual Windows file server is attempting to connect to workstations, on the same subnet, through local TCP port 88. The IPS systems
that we have in place on the workstations in our organization are detecting these connections and is blocking them by
considering them port scans.  The connections are incoming from the file server to the workstations.

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?

Thanks!

I'd give MSofts Port Reporter and its Parser a try:
Overview
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
