SP2 and home networking

I'm running XP Home Edition and finally got around to installing SP2. Here's
the problem.

I have a Cisco wireless router. The machine that I just upgraded is
hardwired to the router and there are three other machines connected
wirelessly (2 @ XP home, 1 @ XP Pro). My printers are connected to this (the
hardwired) machine, and I share them with the other computers.

Everything worked fine until installed SP2. Now, even though my machine
shows the printers as shared they cannot be seen by the other computers.
Also, I can't access any of the shared folders from the other machines. I
can see shared folders on one of the other machines from this one, but not on
the others. There is no problem with the internet sharing.

Anybody have similar problems? Is this a security issue? Do I need to
reinstall the network? I ran a system restore back to SP1 everything was OK
again. I may have to just go back and be happy.

Thanks
Mike

PS ...
I just discovered that when I try to disable the Windows Firewall I get a
message:
"Due to an unidentified problem, Windows cannot display Windows Firewall
Settings."

What's with that?
Can this have something to do with my NAV setup?
