Other Computers in Workgroup can't access mine.

[BradleyHills]

I have 3 computers all running Win XP Pro. All of the computers can see
each other in "View Workgroup Computers" but access is denied to one of
them (we'll call it computer A). Computer A can access all shared files
and folders on both the other computers, but when I try to access
Computer A from either of the other computers it denies access. I've
disabled all the firewalls and have been trying to find something to
fix this problem to no avail. This is a big problem because the
computer A is the main computer with the printer attached to it, and
I'm unable to share my printer over the network as well. Please help.

I'm using a wired Linksys router if that helps at all.

Bradley,

One of the best known causes of this problem would be a misconfigured or
overlooked personal firewall, or another security component. There are more
possibilities though, and any might be the cause of your problem. Read this
article with an open mind.

Are you using Simple or Advanced File Sharing? This may make a difference.

For more direct help, provide "browstat status" and "ipconfig /all" from each
computer, so we can diagnose the problem. Read this article, and linked
articles, and follow instructions precisely (download browstat!):
