Subject: Unknown App


Hello,

During a recent pen-test, I discovered that port 80 is opened by an unknown application on multiple client workstations 
(WinXP).  No web server appears to be running or installed - I've tested a few things, but I'm curious what the list 
thinks is the best next-step to take.
Thanks,
