I have a Windows 2003 domain and have just recently installed Vista Ultimate on a laptop with wired and wireless network adapters. When using ethernet, I can log into my domain account without any problems, but when logging in via wireless, Vista reports that there is nologon server to authenticate with. In what might be a related problem, my wireless computers don't display my wired computers in network neighborhood, and vice versa. My wireless Windows XP laptop can share files and folders with wired computers on the network, but you first have to search for the computer on the network. My Vista laptop cannot. Any ideas?

Are you control sharing and finding (sorry maybe this names are wrong, i am using Turkish Vista) optinons ? If you look at that are youmay find something about your problem...(Actually some security options too )
