SBS 2008 RWW Error 50331688

I recently updated the certificate for OWA on an SBS 2008 installation. That went fine and I deleted the old certificate. A few weeks later, we were informed that Remote Web Workplace was not working. When users attempted to connect to their computer they got a Javascript dialog box with error 50331688.

The cause of the issue is a certificate not being installed for the Terminal Services gateway. The Terminal Services gateway is used by RWW. The fix is to select a valid certificate and then all is good.

To fix the issue:
  1. Open TS Gateway Manager from Administrative Tools.
  2. In the left pane, right-click the server and click Properties.
  3. On the SSL Certificate tab, click Select an existing certificate for SSL encryption and click Browse Certificates.
  4. Select a valid certificate and click Install.
  5. Click OK to close the properties of the server.
All done. It should begin working immediately.
