WHS computer can be seen and accessed, but it cannot access other computers on network

I have a small home network with 2 computers running Windows 7 and one running Windows Home Server. For over a year everything has been working fine. Recently though, all of the sudden, the WHS machine is unable to access the other 2  Win7 computers on the network through file sharing. It can see all the computers, including itself,  in the workgroup (named WORKGROUP), but trying to access the others generates the error:

\\*servername* not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The specified network name is no longer available.

I am using the same user account with the same password and administrator privileges on all three machines. I know the other 2 machines are set up correctly because they have no problem accessing their shared resources with one another. They can also see and access the WHS machine with no problems.

So, why can't i access the Win7 computers from the WHS computer?

    Have you tired restarting the server and the windows 7 systems?
    Maybe a simple reboot could fix it refresh it?
    Try removing it from the domain and readding it to the workgroup.
    Check if the network adapter has acquired a tick next to the allow other network users to connect through this computer's internet connection and remove the tick
    try typing in from WHS system to windows 7
    \\computername\share /user:username   command
    Hopefully one of those fixes it

    Thanks for the suggestions. Unfortunately that didn't solve the problem. I have seen some people on other sites mention that Netbios could possibly have something to do with this, but since it was working before, I'm not sure why I should have to change anything?

    This seems to me like an update issue. Have you installed any recent updates on your Windows 7 machine?

    Just to recap.

    From WHS:
    1. Can you ping the win7 machine?
    2. If you try to remote to one of the win7 machines, does it work?

    On Windows 7 Machines
    1. Is the firewall turned off?
    2. What permissions have you got setup on the shares? Have you tried adding the "Everyone" object with full permissions?
    3. Also try to Enable file and printer sharing and see if it resolves the issue

    Just another question. Have you got any Anti Virus installed on the machines that might be blocking the connection. If you do have an Anti Virus, try disabling it and let me know if it resolves the issue?
