Failed Authentication Attempts Check

Microsoft.SystemCenter.ManagementServer.Security.FailedAuthenticationCheck (UnitMonitor)

Monitors failed authentication attempts to this management server.

Knowledge Base article:

Summary

One or more attempts by a device, a connector, or an agent to authenticate to this management server failed.

Causes

The authentication failures could be due to one of the following causes:

The remote certificate was not trusted
A device is pending approval
The certificate is not imported correctly
The management server and the computer attempting to authenticate are configured to use different authentication settings

Resolutions

View the details for the alert to identify the event that triggered the alert.

For event 20072: View the details for the alert to identify the computer that is using an untrusted certificate. Configure the source computer to use a trusted certificate or configure the server running Operations Manager to trust the certificate authority that issued the certificate. For information about configuring certificates refer to the following:

Managing Certificates in Operations Manager ( http://go.microsoft.com/fwlink/?LinkID=824998).
Managing Certificates from the Windows Server topics on TechNet ( http://technet.microsoft.com/en-us/library/cc771377.aspx).

For event 20002: Open the Administration area in the Operations console and click Pending Management. Select objects listed and click Approve or Reject, as appropriate.

For event 21003: Ensure the root certificate of the Certificate Authority that issued the certificate for the computer identified in the alert details is imported to Trusted Root Certification Authorities . For instructions on importing a Trusted Root certificate, see the topic for your type of certificate authority in Authentication and Data Encryption for Windows Computers ( http://go.microsoft.com/fwlink/?LinkId=161162).

For event 21011: Check the authentication settings for both computers in Group Policy and Local Security Policy.
