Resolving WMI Access Denied

If you’re experiencing “Access Denied” errors when attempting to discover machines with WMI in vScope, there are several potential causes. Follow these steps to troubleshoot and resolve access issues.

Ensure that the account used for WMI discovery has the necessary permissions to read information from the target machine(s). For detailed instructions on configuring local accounts for WMI access, refer to Setting Up WMI Access via AD GPO.

  1. Check that the password is accurate and hasn’t expired.
  2. Update the password in both vScope and Active Directory if needed.

A significant time difference between the vScope server and the target machine(s) can cause authentication failures. Ensure the local time is set correctly on both the vScope server and target machines.

Verify that NTLM is enabled on each target machine, as WMI authentication requires it. Disabling NTLM can prevent WMI connections from establishing successfully.
