Hello! I've recently installed Windows 7 on my 2 machines at home. I had a few teething problems (as expected) but I've managed to sort everything out. My only problem now is that my other machine just does not want to join this machine's homegroup. I've tried alot of things, and tried everything the troubleshooter has to offer, including the web time synchronization, to no avail. I suspect it may be because of the way I have my network set up - Each machine does not connect directly to the router. I have this machine which connects to the router, and I have the other machine which connects to this machine (the motherboard has 2 sockets for network cables) which enables it to connect to the internet and my network etc so long as this machine is switched on. I would appreciate any advice - thanks in advance! P.S. I have no yellow exclamation marks in my device manager, and I have attatched my dxdiag just in case.
