Thank you Tim!  I installed TDIMon and found the app
ssdpsrv was beeing accessed by two remote addresses.
After a little poking, also found an app called
BackWeb installed.  Is this a standard install on
systems with factory installed software?  The PC
vendor couldn't tell me anything (surprise ;)...

Grab a copy of TDIMon from sysinternals
(http://www.sysinternals.com/tdimon.htm).  You can
use it to view tcp and
udp services under windows.  With it running, you
can telnet to each port
on the local machine and tdimon will tell you what
application answers the
call.

I just purchased a new HP PC and it starts up
listening on port 5000 tcp and udp port 1900 even
after completely reloading from the recovery CD's.
HP tech support said to contact my internet provider
since I have a dsl connection. They could not give
me any explanation as to why these ports were open
even when installed and not connected to the
internet. Once I did discover this I installed an
IDS and immediately started getting udp port probes
from a specific address. Any idea's or suggestions
would be appreciated. Once connected to the internet
here is a netstat -an:
