Cannot access computer on 3 PC network

[Guest]

I have a 3 computer network with my main desktop PC connected to a linksys
WRT54G wireless router. A wireless notebook and another wireless desktop.

All 3 computers are able to access the internet.

The 2 wireless PCs can see each other, share files and printers and access
the internet. The desktop that is wired to the router gives me an "access
denied work group not accessable" error. I have windows firewall turned off.
I've tried turning off and uninstalling norton personal firewall and still
cannot get it to work on my network.

This network worked fine prior to doing a clean install of XP Pro with SP 2.
I have tried running the network setup wizard.

HELP!!!

I've had exactly the same problem, and Hans-George's site sorted it - after
16 hours trying everything I could think of and find.

Go to his site, or try this:

You have all the following symptoms:

You can ping the computer by IP and by name.
When you type: net view \\computername, you get the error message, "Error 5:
You do not currently have access to this file. The file may be marked
read-only, or it may be part of a shared resource such as a folder, a named
pipe, a queue, or a semaphore. You can use the ATTRIB command to change the
read-only attribute, or try again later when the file may be available."
This is in some cases caused by a registry setting named RestrictAnonymous.
Go to the computer which you cannot access, start a registry editor and
change the following registry value.

HKEY_LOCAL_MACHINE
\SYSTEM
\CurrentControlSet
\Control
\Lsa
Value name: RestrictAnonymous
Value type: DWORD

If the value is 1 or even 2, change it to 0, reboot and retest. If the
problem is solved, leave the value at zero. If not, you can change it back if
you like.

Background: RestrictAnonymous controls whether null sessions, sessions that
work without any authentication and use the permissions of the groups
Everyone and NETWORK, are allowed (value 0) or disallowed (value 1). The
value 2 is obsolete for Windows XP.

Don't mistake this for the value named restrictanonymoussam, which controls
null session SAM account name listings.

The man is a GENIUS!
