Windows update is one of the more important features of SCCM. Keeping all servers and workstations in your environment up to date is most important.
I met the following error while SCCM 2012 was trying to update one of my servers.
You try to push Windows security updates to a remote machine, but Windows update fails.
In ScanAgent.log you may see the same error 0x80072efd or 0x87d00631
WindowsUpdate.log may contain lines with entries like: ‘Last proxy send request failed with hr = 0x80072efd’
Probably the proxy settings on the remote client server are incorrect.
Check if Proxy settings on the remote client server are correct by running the ProxyCfg.exe tool.
In CMD windows type: ProxyCfg.exe
You should get a ‘Direct access (no proxy server)’ result, and not the above result.
Be aware that ProxyCfg.exe has been deprecated In Vista and above. it is replaced by the Netsh.exe winhttp commands: netsh winhttp show proxy
Run ProxyCfg.exe -d to remove the unwanted proxy setting (Direct Access).
I hope this has helpful for you.
