Windows 7: Win XP pc cannot access win7 user restricted shared folder

I have 10 pcs on a LAN workgroup. They are mixed Windows 7 and xp. I have set the file sharing, net discovery etc on win 7 on and password protection, firewall off. They all have user accounts like pc1, pc2,...pc10 and I have also created the account of the pc I want to access the restricted folder to the pc that shares it. I have set the ownerships on Windows 7 machines too. I can access the folders on XP machines from the Windows 7 successfully. When I try to set a user-restricted shared folder to a Windows 7 pc and access it from XP I fail. It says that I do not have sufficient rights to access the folder, contact the network admin. I can only access to the folder by setting it available to "everyone" or "guest" read/write but that s not what I want... :-( any ideas guys? I have tried so many times the last 5 days withou luck... Any help would be highly appreciated! Thank you all!

You need to make the special User a member of a restricted access group, the link below explains the details of how to set this up.

Hello and thanks for taking time to answer my post!
This is for restricting folder access to local users. I am talking about network users that try to access the folder over the LAN. I tried what this tutorial said and still fail to access from a XP machine. Any other ideas? :-)

Are you logging into the 7 PC with a Username and password that has Admin right? If you are then you should have access to all files and folders that user has on the local machine.

In order to set up special shares for any LAN user you must first set up a standard User account on your machine for the special user in order for that Users name to show up on the list for advanced sharing. Once they are on the list you can add the User to a restricted User group which has sharing restrictions set up. Although I'm not completely sure how XP fits into this tutorial I'm sure there is a way to make it work.
