SBS 2011 Remote Access Buttons Not Working - Event ID 3 and 1309
To work around the most common cause - less than 5% memory available and the gateway service stops being available for incoming requests and usually after installing .NET Framework 4.5.1.
- Edit the web.config file in "C:Program FilesWindows Small BusinessServerBinWebAppRemoteAccess" folder.
- Search for the line "<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />".
- Add in minFreeMemoryPercentageToActivateService="0" after the "true" and before the " />" so it looks like the following "<serviceHostingEnvironment aspNetCompatibilityEnabled="true" minFreeMemoryPercentageToActivateService="0" />".
- Restart the WWW Pub service which will also require RD Gateway service to be restarted.
