From: "Robbin Meng [MSFT]" on 27 Jun 2010 23:15 Hi Richard, Thanks for your update. Besides the firewall factor you mentioned, it is also necessary to troubleshoot the remote workstation web browser(IE) and RDP( 6.1 client or higher )installed on the remote workstation. That's why I'd like you check and upgrade the RDP version and reset the IE settings and register the "Mstscax.dll" dll on that remote workstation. Regarding other thoughts, here are some general information of RWW for your review reference: Windows SBS 2008 sends all new users a "Welcome" e-mail that introduces them to the network features including Remote Web Workplace. Before users can access Remote Web Workplace, network administrators must satisfy the following requirements: " Users must be members of the Remote Web Workplace Users or the Domain Admins security groups. " Windows SBS 2008 must allow connections through TCP ports 80, 443, 987, and 3389. " The computer used to connect to Remote Web Workplace must allow connections through TCP ports 80, 443, 987, and 3389. " Routers on Windows SBS 2008 must be configured to forward Internet traffic to TCP ports 80, 443, 987, and 3389. 443, 4125 are open on your Internet firewall. " The browser used to view Remote Web Workplace must support and accept cookies. Otherwise, Remote Web Workplace refuses the connection. " Clients are running Internet Explorer 6.0 SP2 or higher " The RDP 6.1 client or higher is installed on the client machine " The client must trust the SSL certificate that is installed on the SBS Web Applications site Prerequisites for accessing Remote Web Workplace http://technet.microsoft.com/en-us/library/sbs-2008-remote-access-management(WS.10).aspx RWW in SBS 2008 leverages the TSGateway service that is running on the SBS server to perform the remote desktop connection to the chosen machine. Like RWW, TSGateway is fully enabled when the IAMW is completed ("Add a Trusted Certificate" must also be completed if you are using a 3rd party SSL certificate). This allows remote desktop connections to your domain-joined machines through port 443. This is different from RWW in SBS 2003, where you had to open port 4125 through your firewall.
