Hi, I started the client and had it running fine. I quit the client and then rebooted the server (separate machines). Upon the server restarting, I restarted the client but it wouldn't connect. Looking at the server console it appears the extension is already registered which leads me to believe that there's a service hanging around on the client PC which re-registered itself when the server restarted. Can someone tell me what executables and/or dlls are supposed to be running or called by the client and hence potentially visible in the task manager so I can check whether this is another bug? Cheers, Mike.
