Has anyone know of any issues with SBS 2003 Standard where they cannot connect to desktops or servers remotely (RDP) through the remote web workspace, between a set time? This may sound odd, but a fresh SBS 2003 Standard install, and sometime between the hours of 16-1630 and 1700hrs each day, Remote Web workspace refuses to let us connect to either desktops or servers. We've checked the router, using Draytek 2800, and all known ports forwarded correctly. If we VPN to the server, then start an RDP session to either desktops or server it allows us to connect ok? but RDP works perfectly up until this time. Cant find anything in the event logs at the time to suggest something is wrong, and using netstat, nothing uses port 4125 at the time either. When attempting to connect 4125 show's my IP address as established. I checked the process that uses 4125 at the time (w3wp.,exe) - running issapp.vbs showed it was linked to the DefaultAppPool application pool. I through that maybe recycling this application pool might have fixed it but no, still cannot connect. This odd thing about this problem is its now just started to happen to another known SBS 2003 Standard Server that has good health.
Any thoughts welcome.
