EFW showing local hosts as P2P server. Why?

The Traffic Analyzer (ntop) shows several of out computers as P2P servers.  Even the EFW shows up as a P2P server.  Our file server shows up as a P2P server also. 

I don't see any P2P software or services running on those workstatons unless they are 1) hidden (running under different name) or 2) spyware/malware etc.  We have a software firewall on each workstation as well as Anti-virus/spyware.  The anti-virus/spyware scan runs nightly on each workstation so I am fairly confident that they are clean.  We are using EFW 2.2 rc3

Anyone else experiencing this same issue?  Does it have to do with a specific ports for windows (samaba) file sharing being open?  How about Windows Messenger?

I suppose that ntop detects destination ports used by file-sharing programs, and mark that traffic as P2P. If you use Skype or another program that uses a wide range of destination ports, its traffic can be marked as P2P.
