If you are, and have ever installed a fresh Windows workstation into a domain, or want to switch domains, you may have experienced the phenomenon where the first time you try to log in to the new domain, it takes a long time, I mean minutes, to generate the list of available domains from the Domain drop-down box. This has happened to me on several occasions, regardless of proper DHCP, DNS, etc., settings.
I have found the fix to be to log in with the DOMAIN\username syntax. Instead of taking a chance of being greeted with “Please Wait While Domain List is Created” for several minutes, you can specify the domain you with to log on to in the username box. Without exception, this has resulted in instant logins for me.
