RWW Problem

Yesterday, we had a problem with remote web workplace on a SBS 2003 box. The site itself was accessible without issue, but when users were trying to connect to client PC's, they were getting the error:

Connectivity to the remote computer could not be established. Ensure that the remote computer is on and connected to the Windows Small Business Server network.

I checked to make sure port 4125 wasn't taken over by anything else such as mad.exe and found one of the PC's on the network was connected to this port through port 445. I rebooted this machine and re-run netstat -aon, finding port 4125 was listening for this machine again. Eventually it cleared but RWW still took ages to start working again.

Does anyone have any reasons as to what this client PC could have been doing and why?

    Accepted Solution

    Very odd that it would be switched to 445, but might updates have been applied to the PC? A couple of Windows updates disable remote access until the PC or server has been rebooted a second time, even though all other functions work properly. When applying updates to servers it is good to have an alternate access method, such as VPN, just for this reason. PC's are usually less critical.

    Very strange, it hasn't happened again so i can only assume it was just 'one of those things'. Thanks for your response though
