So you want to connect a Windows 2008 to a SBS 2003?
If you are testing Windows 2008 and want to attach it to a SBS 2003… don’t use /connectcomputer it’s won’t work. Use instead the manual domain join method. Go into the System properties and place the domain info there and join it manually.
We also still have questions about how to get TS licensing set up on the member server box… so hang loose on that one for now.
