We have a home network, consisting of just two PC's. Computer A is the host,
and Computer B is the second PC. Both run Windows XP Home edition, SP2.
Computer B has McAfee security system.

Everything worked fine on Saturday night. Computer B was 'on the road' on
Sunday/Monday, and used an in-room internet connection in a hotel. On Sunday,
Computer A installed Symantec's Norton Internet Security (NIS) 2006. On
Monday night, when Computer B returned home and connected to the home
network, it was able to easily connect to the internet (cable modem through
Computer A), but has not been able to print on the network printer. Computer
A can print fine. We have tried the following: remove NIS using add/remove
hardware utility -- no luck. Re-install NIS - no luck. We have called
Symantec Tech Support, but have not been successful with their suggestions.
They did suggest a 'clean boot', which we have not tried.

We definitely do NOT want to mess up the internet connection for Computer B.
We'd rather have a successful internet connection for Computer B than a
successful printer connection, but it would sure be nice to get back to where
everything works again.

Computer B can successfully ping both Computer B and Computer A. Computer A
cannot ping Computer B, but can ping Computer A. Is the problem with Computer
A or Computer B? And what should we try next?

Thanks for any help you can provide.
