v8.1 on Windows 2008 32-bit web client throws error before getting to login screen

In loading v8.1 on a Windows 2008 32-bit server, I could not get the web client to run.  Before getting to the login screen, it would throw this error:


HTTP Error 500.19

The requested page cannot be accessed because the related configuration data for the page is invalid.

The configuration section 'system.web.extensions' cannot be read because it is missing a section declaration


Tried a few suggestions from support, but it still failed.  Applying SNC02, Web Core 02, and Web Model 01 did not fix it either.


This web.config modificaiton fixed the problem.


I added the "sectionGroup" as specified in the article inside of the existing "ConfigSections" in the web.config.
