Thommo,

Are you running both Client for Microsoft Networks, and File and Printer Sharing
for Microsoft Networks, on all computers? Do you have shares setup on all?

Make sure the browser service is running on each computer. Control Panel -
Administrative Tools - Services. Verify that the Computer Browser service is
started.

Check to see if Simple File Sharing (Control Panel - Folder Options - View -
Advanced settings) is enabled or disabled. With XP Pro, you need to have the
SFS settings the same on each computer.

If SFS is disabled, check the Local Security Policy (Control Panel -
Administrative Tools). Under Local Policies - Security Options, look at
"Network access: Sharing and security model", and ensure it's set to "Classic -
local users authenticate as themselves".

If you set the Local Security Policy to "Guest only", make sure that the Guest
account is enabled, and has an identical, non-blank, password on all computers.
If "Classic", setup and use a common account with identical, non-blank, password
on all computers.

Any firewalls (ICF or third party) on any of the computers? You have to
configure them to allow file and printer sharing by opening the following ports:
TCP 139, 445; UDP 137, 138, 445.

Please provide ipconfig information for each computer, when using wired, and
when using wireless, connections.
Start - Run - "ipconfig /all >c:\ipconfig.txt" - Open c:\ipconfig.txt in
Notepad, copy and paste into your next post.

Cheers,
Chuck
