Di ba automatic na SP2 na if naka Media Center Edition?

Oo yata, pero not sure. Di pa ko nakakagamit nyan e. The SP level should be indicated in Help -> About Windows from Explorer.

Yup, both computers have 3rd party firewalls installed. ZoneAlarm in my desktop and Comodo in my laptop.

Baka nga yan yung problem. If the firewalls are blocking pings, it may be blocking other protocols too kaya sila hindi makapag-file sharing over TCP/IP.
