Windows Update error 0x80072ee2, Windows domain.

Some of the computers on our network are having a windows update issue. The computer will display an error message that windows cannot search for updates, but if you click search for updates, it will find them. I have looked at the windows update logs.

 

WARNING: SendRequest failed with hr = 80072ee2. Proxy List used: <(null)> Bypass List WARNING: WinHttp: SendRequestUsingProxy failed for WARNING: WinHttp: SendRequestToServerForFileInformation failed with 0x80072ee2
WARNING: WinHttp: ShouldFileBeDownloaded failed with 0x80072ee2

We connect to the internet on a proxy, but I dont think the proxy is being used when windows update is run. I can connect to the update link in internet explorer. Very strange issue, if any one has any ideas? We are on windows server 2008 r2, machines are all windows 7 enterprise. Many Thanks.

Windows Update uses winhttp, which has it's own settings - separate to IE.

To see what the settings are :- netsh winhttp show proxy

To see how to set proxy :- netsh winhttp set proxy ?
