We experienced an odd issue today wherein a client trying to connect to a Desktop PC via Remote Web Workplace under SBS 2003 experienced an error.
Despite all necessary Firewall ports being open, and all necessary privileges being given to the user to connect remotely, the client consistently got the error “Connectivity to the Remote Computer could not be established”.
Trying to connect to this PC internally via http://localhost/remoteproduced the same error, ruling out any Firewall issue we’d not spotted.
The answer came by way of a Microsoft Knowledgebase article at http://support.microsoft.com/default.aspx/kb/886209– “Users cannot connect to remote desktops by using the Windows Small Business Server 2003 Remote Web Workplace“
The problem was with another process having snatched Port 4125 blocking RWW from using it. In this case, we restarted the IISAdmin service and the issue was resolved – the end user able to connect to the PC in question via RWW again.
We’ve now made the necessary registry changes documented in the article and have scheduled a reboot for the server out of hours to ensure the problem doesn’t re-occur.
