2 network pc's problem

[Guest]

I have a two-computers network in my house, both are running the same
operating system (WinXP, SP2), connected using a 4-port DSL router. Both can
view the workgroup computers correctly.
Computer A can access B (and use its shared files), while computer B can't
access A. I tried all firewalls disabled (even the router's) and "File and
Printer Sharing" is enabled; there are shared files and folders on both
machines, with sharing level "Maximum Allowed".

Microsoft Firewall and Zone Alarm Pro firewalls are installed on both
machines, but are turned off. Norton Internet Security 2005 is installed on
B Only. There is no other third party software installed on either.

Computer B can ping successfully on A by either ip or name, but not
accessing it. Any idea how to solve this problem?

Thanks for help!

OK, with both computers able to ping by address and name, and with one able to
access files, you probably have a misconfigured firewall, or other security
component. Go thru this troubleshooting guide first.

Remember that disabling personal firewalls (and Zone Alarm is known for this)
won't always be a good solution. And look out for firewall components in your
antivirus (anti worm protection).

And look at "browstat status", "ipconfig /all", "net config server", and "net
config workstation", from each computer, so we can diagnose the problem. Read
this article, and linked articles, and follow instructions precisely (download
browstat!):
