Unable to see the users in "Local users and groups" MMC

    Question

  • Unable to see the users in "Local users and groups" MMC. When we click on groups in MMC it throws the attached error.

    Looks like the computer is not able to fetch the SIDs or something.... Please help!

    This is Windows Server 2008 R2 Sp1

  • If the server is a Domain Controller, there will be no local users or groups. Does this account for what you experience?

  • What if you type LUSRMGR.MSC in Run?

  • as Richard suggested it looks like your server is a Domain controller, if you run LUSRMGR.MSC as ArnavSharma suggests and you are on a DC the error message will say "The computer 'computername' is a domain controller. then you should open the Active Directory Uses and Computers snap-in as the error message will suggest.

    Though if your server is not a DC you should start by analysing you event log.

  • Hi ,

    If this is a DC: If this is a Domain Controller, the you cannot access this sap in.

    If this is not a DC: Please try accessing using LUSRMGR.MSC

    If you still not accessing check if there are any related logs are generating in event viewer.

    Please check and get back to us to provide you the more information.

  • This is a web server and not a DC. When i run LUSRMGR.MSC it opens the Local Users and Groups MMC, but in the users list there is no user available however when you run the command net user you will see the list of all users. And when you click on Groups it will throw you the error as the screenshot provided above. There's nothing in event logs. It was working before and all of a sudden start throwing this error. 

    Please find the content of SAM.LOG file attached.

  • Run following commands from elevated cmd (run as Admin), reboot the server in question and see if that makes any difference

    net localgroup "Administrators" "NT Authority\Network Service" /add
    net localgroup "Administrators" "NT Authority\Local Service" /add

    Also, looking at the snapshot, it appears that some files have gone bad. From elevated cmd, run sfc /scannow

  • The first solution didn't worked. I am a bit afraid about running sfc /scannow because it is a production server. And sometimes after this command the server never comes up. I just wanna know if this command is fool proof.

  • Yes, its safe. You need to reboot once the process is complete.
