    Network Access Denied - but working on other machine?!


    Here comes my problem:

    - I have one Windows 7 Ultimate and 2 Windows 7 Professional in Virtual machines.
    - I have created a user test with the password test on all three machines.
    - The "test user" is member of Administrators on all three computers.

    PC1: Win 7 Ultimate
    PC2: Win 7 Pro
    PC3: Win 7 Pro

    On PC1: \\PC2\c$ --> Not working
    On PC1: \\PC3\c$ --> Not working

    On PC2: \\PC1\c$ --> Working
    On PC2: \\PC3\c$ --> Not working

    On PC3: \\PC1\c$ --> Working
    On PC3: \\PC2\c$ --> Not working

    Other things behave the same. E.g. "shutdown -m \\machine"


    Seems like my PC1 has something set up different. But I can't find it.
    I checked the "Advanced sharing settings" and Local Security Policies.

    EDIT1: \\PCx\Users is working well in any combination.
    EDIT2: And if I remove admin rights from "test" on PC1, the others cannot access
    c$ on PC1 any longer - as expected.

    So the issue seems to be somehow related to the security rights of user "test" on
    PC2 and PC3. Seems as test does not have the same rights there, although being
    member of "Administrators".


    Any ideas are highly appreciated!

    And last but not least: A friend of mine has the same strange thing.
    But he has one Win 7 Pro and one Win 7 Home Premium. Access from one
    machine to the other is fine. But not vice versa.

    Got the solution: Have to turn UAC off, then it's working. VERY weird!

    What also solves the issue without changing the UAC is this REGISTRY-KEY:

    To change this behavior, create or modify the following registry value:
    HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system\LocalAccountTokenFilterPolicy
    --> This is a DWORD value. Set it to 1.

    A reboot is necessary after creating / updating the key.
