I have an outright embarrassing problem to set up a trivial Windows home network. There are two PCs, A running Win XP pro, and B running Win XP home. Both connect to the Internet via a simple wireless router.
I run the network setup wizard on both PCs selecting MSHOME as the network/domain. A can see B in the network but claims it has no permissions to access it (though I've shared some folders "to all"). B can't see A at all. It can't even open the Mshome icon in the Microsoft Windows Network, claiming there are no permissions.
Both PCs run Sygate personal firewall. Other protocols between them work just fine (such as FTP transfers).
What am I missing?
EDIT - Problem solved
It was Sygate: I just removed all filters from it and then when the other PC tried to connect I allowed the process that was asking permission. Now it works fine with Sygate enabled on both PCs.
