Need Help with LAN Problem

[Jim]

I'm running 4 computers (3 Windows XP Pro, 1 Windows 2000 Pro) on a home
LAN. Occasionally I have a problem connecting with one or more of my remote
computers. Not certain what is causing this problem - I sometimes suspect my
McAfee Security Center blocking a connection.

Right now, computer A cannot connect to computer B and visa versa. However,
computer A can connect with the other 2 LAN computers and they in turn can
connect to computer A. All 4 computers can connect to the Internet.
I'm not a wiz at networking but I do have some general knowledge - this time
I'm stumped.

Are there any Network Software programs (free or otherwise) that can easily
diagnose network problems such as I'm having?

Any suggestions would be greatly appreciated.

Jim

Uninstall (not disable) any non-Microsoft firewall software. Configure your
network so that it's working correctly. Then reinstall the
firewall/security software and it should see and allow (or allow you to
correctly configure) your existing, working network connection.

I removed the McAfee firewalls on both computers.
Many thanks Richard, that did the trick.
