Network problems after installing SP1

[Jujoos]

I have 2 home computers and a laptop all networked with a
hub and cat5 cables. The main computer which connects
directly to the internet is running XPhome, as is the
laptop, the other PC is running XP Professional. I have
had no network problems for months until I recently
installed SP1 from the Microsoft site. After
installation tbe internet connection could not be shared
and files on the computers could not be shared. I
uninstalled SP1 and the problem was resolved. I
immediately got an Automatic Windows Update notification
for KB832483 (Security Update for Microsoft Data Access
Components). Being wary, I created a restor point before
installing the update the next day. Once again, the
internet connection cannot be shared and only files
between the 2nd PC which doesn't connect directly to the
internet and the laptop can be shared. I tried system
restore but it won't let me restore to any point before
the update was installed. Can anyone offer anything to
try?

1.not file sharing: make sure no firewall running on the LAN.
2. Internet access: can you ping a public IP like 4.2.2.1? if yes, can you
ping yahoo.com? if not, check the dns settings.
