When users attempts to click on the “Connect” link under “Computers” in attempts to launch remote web workplace nothing seems to happens. If you issue a IISreset then the system starts working again for a short time before starting to fail again. You check your logs and find EventID 1309 Event message: An unhandled exception has occurred.

It appears that it maybe  some level of memory issue in .Net 4.5 and the Remote Access web.config set to default at a given memory level.

To Fix:

Edit (via NotePad) the web.config file located at “C:\Program Files\Windows Small Business Server\Bin\WebApp\RemoteAccess

Look for the following line at the bottom of web.config

<serviceHostingEnvironmentaspNetCompatibilityEnabled=”true” />

Replace that line with: (all on one line)

<serviceHostingEnvironment aspNetCompatibilityEnabled=”true” minFreeMemoryPercentageToActivateService=”0″ />

Save file and then restart the World Wide Web services to activate the changes.

Your Remote Web Workplace should now stay functional.

Enjoy..
