Note:  If a Windows user does not have local administrator rights, the user can use the Run As feature within Windows to run an application as a local administrator without granting the user the rights.

To check if the Windows user is a local administrator or has local administrator rights, follow these steps:

  1. Determine the computer name.
  2. Determine the user name and domain.
  3. If the domain (from step 2) is the same as the computer name (from step 1), the user is logged in locally.
  4. Right-click My Computer and select Manage.
  5. Expand the Local Users and Groups: 
    • Windows Server 2012 and Windows Server 2012 R2 this is found within Server Manager then Select Tools > Computer Management
    • Windows Vista, Windows 7, Windows Server 2008, and Windows Server 2008 R2 this is found within Configuration
    • Windows XP and Windows Server 2003, this is found within System Tools
  6. Select the Groups folder.
  7. Double-click the Administrators group from the right pane.
  8. Look for the user name in the Members frame:
    • If the user has administrator rights and is logged in locally, only his user name displays in the list.
    • If the user has administrator rights and is logged into the domain, Domain Name\User name displays in the list.
    • If the user name is not present, then the user does not have administrator rights.

If the user is not a local administrator and should be added, follow these steps:

  1. Click Add.
  2. Click "Locations...", select the domain found in step 2 from the above steps, and click OK.
  3. Type the user name in and click "Check Names" or click "Advanced..." to search for the user name.
  4. Click OK to close the Select Users or Groups window.
  5. Click OK to close the Administrator Properties window.
  6. Close the Computer Management console.
