home networking win xp sp2

I am having a problem networking, and the problem appears to occured after installing SP2 on one of the computers. I had no problem networking (sharing files and printer) prior to installing SP2.

I have a 2 computer home network using linksys wireless g router. Both computers have the same specs (pentium 3), with one connected by ethernet to the router running Win XP SP2 (main computer) and the other wireless running on Win XP SP1 (comp 2). I have run the "set up home network" wizard on both computers to make sure set up is correct and network name is the same. I have gone into the exceptions tab under Windows Firewall in Windows Security Center and checked the UPnP framework (under Programs and Services). File and printer sharing was already checked.

The main computer recognizes both computers in the My Network Place "Work Group Computers", but I cannot ping Comp 2. I cannot access the shared files.

Comp 2 can ping the main computer, but does not recognize it in the My Network Place "Work Group Computers". I cannot access the shared files or print.

I am at a loss other than uninstall SP2. Has anyone had this problem? What is the solution?

Any help is appreciated.

 

Try turning off your firewall completely. This is usually the problem. Also, make sure that the main computer can access the internet.
