Just an update ...
I found that WU had installed a newer version of ASP.Net (4.5.2). I rolled it back to v4.1 and still no joy. Had to go back to v4.0 only and the site started working again as required.
The question still remains though, what adjustments to the web.config must I make to enable the REST API services to operate under the newer version of .Net?
