We've recently setup a new domain on our office network and joined all laptops to it. When I log onto Windows 7 while plugged into the network, I pass the logon screen and the Welcome screen within seconds (I have a SSD). When I'm on wireless at home or elsewhere (not on the domain network), it takes forever to get past the Welcome screen. This also happens to everyone at work in the same scenario. We believe it might be a DNS issue. Anyone have any ideas of how to diagnose the issue?
