System Center 2012 Configuration Manager - Software Update Point Monitoring Failing

2014-11-08

From the archive (2014). Written for the tools of the time, so some details may be out of date.

Recently had an issue with my lab where my HTTPS Software Update Point was throwing some errors.

The SMS_WSUS_Control_Manager was show that it was failing to monitor the WSUS Server.

WSUS Control Manager failed to monitor WSUS Server “CM04.LAB.LOCAL”.

Possible cause: WSUS Server version 3.0 SP2 or above is not installed or cannot be contacted.
Solution: Verify that the WSUS Server version 3.0 SP2 or greater is installed. Verify that the IIS ports configured in the site are same as those configured on the WSUS IIS website.

On the actual server hosting the SUP, the WSUSCtrl.log was showing the following error: “…the request failed with HTTP status 401: Unauthorized”

The following Microsoft KB help me resolve the issue:

I used Method 2 since it was just my lab.  Disabling the Loopback check. After making the necessary registry change, after restarting the server, everything was reporting correctly and the WSUSCtrl.log was coming up clean.
