WSUS - An HTTP error occured

In the process of setting up a new WSUS server I received the following error message when attempting to perform a sync.  This is after installing WSUS 3.0 Service Pack 2 available from http://support.microsoft.com/kb/2720211

An HTTP error occurred

Clicking Details provides the following error output.

WebException: The request failed with the error message:

After researching this error message I discovered Microsoft moved data on the Microsoft Update servers early 2013 and as a result the WSUS installation package which comes with Windows Server 2008 R2 no longer knows the correct URL to synchronise with (this is after installing WSUS 3.0 SP2 from KB2720211).

After installing WSUS 3.0 SP2 from KB2720211 you then must install another critical update which can be downloaded from KB2734608.  This will tell WSUS the new location to synchronise from.  In total you should have installed the following two updates including the Report Viewer 2008 package.

Download KB2734608: http://support.microsoft.com/kb/2734608

After installing KB2734608 on my WSUS 3.0 Service Pack 2 server, WSUS now referenced the right Microsoft Update location and synchronisation started working successfully.
