One Computer Cannot Join Workgroup

Hello,

I have been working on this for a while and have tried many things including registry edits, verifying NIC properties, running a repair install of Windows XP, etc. No dice.

I have one computer on a small network running Windows XP that will not allow files to be read from other computers or vice versa. From the my network places, on other computers in the workgroup, the computer in question shows up, but when clicking on it gives the message basically saying cannot connect... may not have necessary permissions to connect. I've tried fixing permissions on the computer in question too. Also, I have disabled and tried uninstalling firewalls on the computer in question.

What is strange is the computer in question is able to connect to our Linux Server and it is also able connect to the internet.

We have a couple other Windows XP computer and a Windows 2000 computer. I also just installed a Windows 7 computer and with one tweak to the Windows 7 registry, I was able to get it to be accessed on the Workgroup. Why the existing Windows XP will not all other computers to be accessible to it, I have no idea at this point. It's frustrating.

I've been thinking it could be a blocked port through our router, but why would the Windows 7 machine work if that's the case?

Thanks for any assistance!

I forgot to mention, I have verified the Workgroup name is the same on all the computers... I would think it would have to be if the computer in question shows up on the other network computers.

I also forgot to mention, when opening up My Network Places on the computer in question, the only computer that shows up is the computer in question. Again, the computer in question does show up on all the other network computers though.

Is the firewall enabled or disabled?

Thanks for the responses. I have not had a chance to work on the issue lately. It is not a top priority at work right now. I will get back to working on the issue as time allows. Thanks again for the suggestions!
