    hi --today websites on our server started throwing 401.1 Not Authorized
    error. We checked several things but no help. Finally found that network
    users are denied access on the system (since IIS anonymous users access
    sites via network rights). Using "Local Security Settings" MMC we navigate
    to Local Policies > User Right Assignment. Double click on "Access this
    computer from network" and add "Everyone" to it. When this is done, sites
    start to work properly. After few minutes sites again stop, when we check
    local security setting our settings are vanished and "Access this computer
    from network" is blank!

    This problem is driving us nuts beside costing business since client's sites
    are down. We checked server, there is not virus etc. Any help is
    appreciated, we are will to pay for help.

    Thank you!

    It sounds as though you have a Group Policy operating that is controlling
    the User Rights. Someone must have added the policy to AD for this to start
    As it happens, one of the MS security templates does this, so maybe, just
    speculatively, someone has applied this template.
    To test this, make sure in AD that no policies are being applied, and amend
    the local policy manually. However, you need to be very sure that you have
    the correct security settings afterwards and not just open it up to get it
    to work.
    Also make sure also that full security auditing is turned on, and see where
    it is failing.

  4. I was having this problem with an XP workstation in my schools domain. I checked all the group policies which were fine. Finally I found out that the access this network from network keep going blank because of a trojan that was installed on that computer. Just delete the trojan with your anti virus and do all windows updates and all should be good. - .NET Developer Portal of Choice
