Description

The following information is for Scan Diagnostic purposes only, and is not indicative of a detected vulnerability.

The scanning user encountered an authentication error when connecting to the WinRM Service. This can be caused by a number of issues:

  • The Credential used may not be valid
  • If the Credential is a local admin account it may not have the LocalAccountTokenFilterPolicy registry key added to disable UAC
  • The Credential is not part of the required administrator group

WinRM access is required for accurate Windows Policy assessments, it is used to collect information on hardening compliance, amongst other Windows configuration data.
