Hello, I have several pc's in a workgroup. If you browse from a pc with windows 7 to a pc wth xp then there's no problem. But from a client with W7 to another client with W7 it works sometimes but most of the time it doesn't. I've already tried the following things: - Removed "remote differential compression" - Unchecked IPv6 - disabled autotuning - changed the LMCompatibilityLevel to 1 Nothing works. Does anybody has another idea?
