I just had to do a system restore point on my wife's computer due to a bad printer driver. Now she can access the internet just fine, but can't access any shared files or printers on the other machines. When I try to browse the network places, it gives a "MyWorkGroupName is not accessible" error. I've checked that it has the correct workgroup name. I can ping back and forth just fine. I just can't access shared files and folders in either direction. What dumb thing am I missing here?
