Found the fix for an error in my Windows logfile on Jeff Guillet’s Blog here but I will repost the instructions just in case that link goes bad for some reason.
Basically, I have a WSUS 3.0 Server that had this error in the event log:
Event Type: Error
Event Source: Windows Server Update Services
Event Category: Clients
Event ID: 13042
User: N/A
Computer: WSUS01
Description: Self-update is not working.
To fix the issue, follow these steps:
- Open IIS Manager and ensure there is a Selfupdate virtual directory in the Default Web Site. If not, create it with the Local Path pointing to C:\Program Files\Update Services\Selfupdate
- Click the Directory Security tab and ensure that Anonymous Access is allowed
- Restart IIS
Verify that the problem is fixed by running the following command at the command prompt:
C:\Program Files\Update Services\Tools\wsusutil.exe checkhealth
Then examine the Application event log for the following event:
Event Type: Error
Event Source: Windows Server Update Services
Event Category: Clients
Event ID: 10000
User: N/A
Computer: WSUS01
Description: WSUS is working correctly.
As background, WSUS clients must connect to the SelfUpdate virtual directory to check for a new version of the WSUS client before checking for new updates. This always happens anonymously over port 80, even if WSUS is configured to use a custom port, such as port 8530.
NOTE: You may have to restart IIS on the server for the changes to take effect. I did.
