Avast Firewall.

Reading through my firewall logs and I noticed theres been alot of activity from the other laptop being on, (Also had AIS running on Winxp SP3)
Questions:
1: Why is the laptop constantly trying to connect to my desktop when scans have come up clean.
2: Why doesn’t Avast Firewall show all the connections across the main Processes on XP, shows them all on Win7.

  1. could be windows file share?

Not quite sure, and the requests are every few minutes with about 4 requests.
