ConfigMgr Scan failed with error = 0×80240438
If you use a Software update point for patch management, you might meet a scan problem when Forefront TMG (in my case) or another firewall is in place. Today, when I deployed a group of updates I’ve seen in the monitoring workspace that all target PCs are in the Unknown tab, so I’ve gone directly in WUAHandler.log and I found these entries:
The same error code in other logs such scanagent.log and updatedeployment.log. On GOOGLE, there is nothing about that. To solve this problem I tried to access from IE to my SUP (http://SUPServer:Port) (8530 in my case) and here I understood what happened. I created a rule on TMG to allow HTTP to the SUP and the issue was gone.
