Win 7 Xp Networking

I have a home net, my win 7 professional desktop is wireless to my Asus DSL-n11 router/modem, my xp pc is wired to the same. My Xp pc can access my win 7 computer no problem and get files, My win 7 computer cannot access the xp pc. The network map on win 7 shows the xp pc correctly placed on the net map, although you cannot click on it, but the pc is not shown under network in 'my computer'. All file sharing is enabled, The net is named the same on both computers and is a work net on win 7. I have been through hours of troubleshooting, web forums, etc., with no success in solving this, it is not the usual simple suspects. I can access the xp pc with remote desktop, but only that way. I think the xp pc is set up correctly, it has that particular needed update and service pack 3 and the net setup wizard has been run. If anyone can help with this I'll be very grateful.

Is the HomeGroup service set disabled on Win7? Do both machines have a User account in common?

My net is set as a a 'work network on the win 7 machine, do i need to disable something too? Both Networks have a common user profile, the xp pc does not require a password to log on and the local security policy for blank passwords has been disabled.

FWIW, I recently had to set up my brothers home network. The way he wanted it was to create some folders on both machines; One windows 7, the other XP. We created a folder on each machine called "<PC-name>-shared" and shared the folder and gave everyone full control. We then went to the other PC and mapped a drive to the shared folder on the other PC.

Works fine.

I know this is old school.

The XP machine was originally on SP2 and did not have the LLTD responder installed, so we upgraded to SP3 and all was well.

Just my 2 cents.

They both have identical work group name, and win7 pc has the net identified as work network, not homegroup. I can not map the drives of the xp machine from the win7 machine, it doesn't recognize it as being on the network, even though it places it correctly on the net map, (you can't click on it, and it isn't listed under network on the computer or user pages.

Go through this tutorial about sharing with XP, click on the XP tab, it should help.
Sharing files and printers with different versions of Windows - Help & How-to - Microsoft Windows

This one is more general but has good info.
Networking home computers running different versions of Windows

It can also help to get around password problems if you use the same username and password on all machines in the LAN.

After going through all of that if you are still having file access problems try doing this registry adjustment on the Win 7 machine with the problem.

Solution is really easy just modify one key in registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
create or modify 32-bit DWORD: LocalAccountTokenFilterPolicy
set the value to: 1

Hello, thanks for your time, I have already been through those two sites, and for sure the compuiters are both set accordingly, I put your registry addition in but no network! Although now when I go to the basic network map , not the expanded map, it shows my gateway as the 'WIGGY' (the name of my net) network instead of 'multiple networks'. My xp pc also sees the net as WIGGY. It's all quite frustrating when those tutorials make it look so easy! I'm new to networking. Perhaps you could do a remote?

So, I got no solution to this problem and the XP pc was seriously lagging anyway so I got another brand new win7 pc, that should make networking easier? HELL NO!! I set up a Homegroup set file sharing up on both pc's, put the password into the other one joined the home group, and now i have one pc that sees its in a homegroup with the other pc and cant actually access it, mean while the other computer doesn't think it's in a homegroup but can access the other!!! Why is microsoft so rubbish???? Do they actually test any of their stuff? I guess now I'll spend another 20 hours trying to make it work
