The client could not connect to the remote computer by using Remote Web Workplace in Windows Small Business Server 2003
If you have ever received this error when trying to connect to a computer via RWW 2003 –
“The client could not connect to the remote computer. Remote connections might not be enabled or the computer might be too busy to accept new connections. It is also possible that network problems are preventing your connection. Please try connecting again later. If the problem continues to occur, contact your administrator.”
There are two possible issues related to it.
1) You have not port forwarded port 4125 ( RWW ) on your router/firewall to the SBS Server.
2) If you have already done that and you still experience the issue, it means that something else might be listening on that same port internally on your server. As Microsoft suggests it might be the Microsoft Exchange System Attendant Service. To find out, use the the netstat command – netstat -aon | find “:4125”. This will show you what is listening on that port. If the command does not print anything, you better check if your router/firewall is really forwarding 4125 and to the right place.
