BleepingComputer.com: My wireless Vista keeps connecting to wired XP

My XP had started acting up so I checked some McAfee logs. Seems My Vista had been connecting to UDP ports on the XP.
192.168.1.4 is the wireless vista
192.168.1.2 is the wired XP
I've done nothing to start these connections. Anyone know why there are being started?

I can give a more detailed logs if required.

IMO, this is normal behavior on a LAN = Local Area Network.

!92.168.1.xxx is a reserved IP range for LANs. Meaning you will never find these IPs on the Internet. To the best of my knowledge all 192.xxx are reserved as well as a couple of other ranges that escape me at the moment.

Unless you suspect infection or someone with another idea chimes in I would not be concerned.

FWIW: May help pinpoint, http://www.iana.org/assignments/port-numbers
