  • Task manager and registry editor disabled by administrator

    Dear Techies,

    I have windows 2003 GC and DC in my environment. From the last couple of Days i am facing some issues with Domain Controller. i cannot access Task Manager and Registry Editor on my Domain Controller it is giving "it was Disabled by Administrator". i think it sounds like a virus issue.

    Even i changed task manager and registry settings in gpedit.msc but no luck, still it is giving same error. I hope their is a possibility to enable task manager and registry editor on my domain controller other than restoring system state backup or reinstalling entire system.

    Any immediate help will be highly appreciated,

    cheers,
    gowtham

    Have you checked the GPO's carefully?

      Can you create a new domain admin account and try logging on with that too?

          •Click Start, Run and type the commands exactly as given below:
          Code:
          REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableTaskMgr /t REG_DWORD /d 0 /f
          
          REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f
          
          REG add HKCU\Software\Policies\Microsoft\Windows\System /v DisableCMD /t REG_DWORD /d 0 /f
          (thanks to Ramesh Srinivasan http://windowsxp.mvps.org/index.html)


          Now hoping the permissions on the registrykey or the Reg command aren't tampered with.

                      Note that the tool REG.exe is not the same tool as REGEDIT.exe.

                      You can also give this vbs script a try:
                      Line 275 left column < http://www.kellys-korner-xp.com/xp_tweaks.htm
                      Login as the infected Administrator and run the script.

                      Another (different) vbs here: WorkaroundsForInternetCafeLockdowns

                      Note, after executing the commands or script you must logoff and on.
                      If still no success, run rsop on the computer for the administrator account.
