Windows update fails with Error 0x80072efd

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.

The problem

You try to push Windows security updates to a remote machine, but Windows update fails.



If you look in WUAHandler.log, you find entries with ‘Scan failed with Error 0x80072efd

WUAHandler0x80072efd

In ScanAgent.log you may see the same error 0x80072efd or 0x87d00631

Scanagent0x80072efd_2

WindowsUpdate.log may contain lines with entries like: ‘Last proxy send request failed with hr = 0x80072efd’

windowsupdate.log

The Cause

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

ProxyCfg

You should get a  ‘Direct access (no proxy server)’ result, and not the above result.

netsh winhttp

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

The Remedy

Run ProxyCfg.exe -d to remove the unwanted proxy setting (Direct Access).

I hope this has helpful for you.
