Hi. Just today I noticed that some of my Windows 7 clients cannot scan for updates. However, others are fine. I can't see what the difference between them is. The boundaries and proxy settings are the exact same on both. This was never a problem, and the only thing I can think of changing recently was upgrading SCCM 2012 to SP1. The SCCM clients are all on the same SP1 version.
In WUAHandler.log you see this on the affected machines:
OnSearchComplete - Failed to end search job. Error = 0x80244021. WUAHandler 11/06/2013 17:09:23 9788 (0x263C)
Scan failed with error = 0x80244021. WUAHandler 11/06/2013 17:09:23 9788 (0x263C)
Other machines are scanning and installing updates fine. From reading about these errors they seem to relate to the clients erroneously going through the proxy to get to WSUS. I can't see why this is the case for some and not for others. On an affected machine I ran a WSUS diagnostic tool, and at the very end, it shows a difference with a normal machine:
Checking Connection to WSUS/SUS Server
WUServer = HTTP://contoso1.contoso.com:80
WUStatusServer = HTTP://contoso1.contoso.com:80
UseWuServer is enabled........................................... PASS
VerifyWUServerURL() failed with hr=0x801901f6
No error description could be found
Does anyone know what could be going on here? In similar instance of this issue on SCCM 2007 some discussion boards mentioned that it was an issue with upper case and lower FQDN formats for the site server name?
