Windows 7: Enter Network Password to access computers???

I created a vpn 'server' on a XP pro machine...I am using a Win 7 Home machine as the Client...I vpn in...goes thru perfect...I cant actually see the computer or get to it by name, I only can if it input the ip \\10.0.0.??? when I do this i get a Enter Network Password...I have tried the user/pass I created for a shared folder on the target machine...i have tried the admin user/pass on the target machine...i made my user/pass on my Windows 7 machine the exact same as the taget machine and nothing works.



whats jacked up is....I have a laptop with Windows 7 on it and it works great...and another XP machine that goes thru perfect as well..

the Windows 7 machine in question I just did a complete factory restore on it and still same thing

i've triedtoo many things to list...from here google...everywhere...plz advise

Everything I've read about this type of name resolution problem on VPN's was because of the client not having a proper DNS address.

You can read more about this problem in the link.

thanks for the link...but i am more concerned about it asking me for a network password and it not accepting anything i try...
