I have two computers connected to a cable modem through a Linksys Cable/DSL Router with 4-Port Switch. I can surf the internet just fine from both computers, but I can't do any file sharing between them. They are both Windows XP Professional SP2 with different computer names and the same workgroup name. When I go under My Nework Places and click on View Workgroup Computers, a dialog box pops up saying, "<Workgroup Name> is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The list of servers for this workgroup is not currently available." It's just a simple home network that I'm trying to build and I have my user accounts on both computers are administrators. How can I be able to share files?

Have you turned on "file sharing" on both the machines?
use the File sharing Wizard if you are unsure of the steps.
Also check the WinXP Firewall that comes with SP2...it
can stop the access as well.

Whelp, I made some progress. When I disable Norton Internet Security 2004, I am able to View the Workgroup but it's empty, there're no comupters in it. I am able to re-enable Norton and it allows me to still view the workgroup, still with no computers listed. Disabling the Windows Firewall did nothing. I even went into Norton's Intrusion Detection and Personal Firewall and typed in the IP address of the other computer as an exception. Still no luck. I do have file sharing turned on with both My Documents folders as well as my printer.

Ok, nevermind. In this time since my last post, I noticed that the shared folders finally poped up in My Network Places. I did have you manually add some of them though by typing in the network address i.e. \\workgroup\folder. Thanks for the replies.
