I am having trouble adding my Thinkpad r50e to my home wireless network on XP.  Permissions not granted.  All sharing options are checked.  I am using a Cisco LinkSysWRT160N router.  My main desktop has 2 way with my kids' desktop, but neither is able to access the Thinkpad.  Thinkpad can use the router and access internet, though.  I am stumped.

Wireless and wired clients cannot see one another on the WRT160N.  This is by design.

Why can I see my Kids desktop wirelessly, but not the Thinkpad?  Both XP, both share internet with the MainPC that is wired to the WRT160N.

Are all pc's in the same workgroup?
Rt. click "My Computer" - Properties - Computer Name
The default for XPHome is "MSHOME" but the default for XPPro is "WORKGROUP"
If you change a workgroup name, don't forget to reboot before the change will take effect...

All are in the MSHOME group.  When I try to search for other computers, the seach displays the laptop.  When I click on it I get a message that reads: " \\laptop is not accessible.  You might not have permission to use this network resource.  Contact the Admin of this network to see if you have access permissions.  The network path was not found."  

Any more suggestions?

sounds like the laptop is setup to restrict anonymous connections try this
start run regedit
navigate to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
on the right side look for restrictanonymous
right click value set it to 0
close regedit and try again.

Hmmm.  I set it to (0) and tried to search for available workgroup computers and was unable to access MSHOME.  So, no progress.  Should I reset it back to (1)?  Can you explain to me what the restrictanonymous setting is designed to do?  Thanks for your help.

It doesnt allow annonymous connections to your computer IE someone it doesnt recognize.  It shouldnt have blocked you off the network thats crazy but yeah go ahead and set it back to 1. well it says the network path was not found but it can view other computer they cant view it correct sounds like a firewall setting.

I tried disabling all my firewalls, and setting the restrictanonymous to (0).  Still no access permissions into or from the Thinkpad.  I am running Norton 360 and it has some pretty complicated exceptions and firewall rules, but I shut them all off to get connected.  Not working.  The Thinkpad is showing itself as a MSHOME computer, but then tells me that it does not have access permissions for MSHOME.

Stumped and stumper

so it also doesn't have permission to access anything on the network or can it see the shares on the other computers and use them they just can't use what it has on it?

No, unfortunately, it is a two way thing.  The Thinkpad is isolated.

Well have you tried the simple things like turn off all the computers at once and bring them up one by one?  Also try start run then type cmd and hit enter in the box type netstat -n a does it contain the name of the computer once or twice? is there one entry with the number <20> next to it?  If there is this computer is trying to be the master browser check with your other 2 and see if any of them have the same result a number <20> next to an entry if it does there is a fight for master browser.  What service pack are all these using do they all have sp2 or is the laptop sp3?

Thanks for the Step-by-step ideas.  I will work them.  The laptop is SP3 and so are the Main PC and Kids PC.  
After exploring netstat, i did not find any <20> lines anywhere.  Honestly, I don't comprehend what i am looing at.

that is an example of what it will look like.

It has also been my experience in the past that norton products cause issues such as this and even stopping them doesnt clear it up usually uninstalling them gets the job done.  If you have the disc to reinstall it there should be no harm in giving it a shot seeing what happens.

try to ping one of the laptops from your pro machine then try to ping both a home machine and the pro machine from one of the other machines.  I would say that your norton firewall is causing the issue even after you turn it off the service still runs and blocks the ports.  Try taking a port scanner on one of the home machines and scanning both a home machine and the pro machine.  I bet you will see that the ports are blocked.  30,449 those should all be open for it to work.

Well, partial success.  I uninstalled SP3 on the Laptop and now it will see and share files with the other two.  BUT... only one way so far.  Main pc can't access the laptop.  For now that is alright.  Should I uninstall SP3 on the other two pcs?

doesnt make sence that 2 sp3 systems share and work fine and one lone one doesn't I would bet its the norton messing with you and uninstalling that would do the trick.  Symnatech programs are a funny creature even when you stop them the service still runs and causes problems but if your happy then i'm happy good luck in the future.
