I recently purchased a Dell Inspiron 1501 with Vista Business & a Dell 1390 WLAN card. My AD Domain Server (Win 2k Server) has a Linksys WRT55AG Router connected via Ethernet.
Here's my problem. All my other computers can connect to the Domain, view shares & join the domain, but not the new Vista Laptop.
I have noticed that NetBios over TCPIP is selected, but when I do an ipconfig /all it says that Netbios is diabled. I have also noticed that Client for Microsoft Networks will not enable. I get a message saying that (paraphrasing here) current configuration requires that Client for Microsoft Neworks be disabled. Possibly these problems are related?
Finally, I have updated the WLAN card driver. I have also disabled the laptop firewall during these tests, so that's not part of the problem either.
