In SBS 2003, we receive the request from remote machine on port 4125 (which opens Dynamically on the server), and after validating the request, we redirect it to the appropriate client machine. Unlike SBS 2003, we do not use port 4125 redirection anymore. In SBS 2008, Remote Web Workplace is based on the TS gateway technology (TS gateway is a part of Windows Server 2008 role suite). However, if the certificates are not configured correctly, you may experience the following issue.
You may get the following error while connecting to the client or server computer, which is inside SBS 2008 network, using Remote Web Workplace:
—————————
VBScript: Remote Desktop Disconnected
—————————
An internal error has occurred (error 50331688). For more information, please contact your network administrator or Microsoft Product Support.
