sbs2k upgrade
couple of other things that get messed up. we had 2 terminal servers with 24 cals a piece installed on them. after removing/adding back into 2k domain, terminal server licensing with only work on DC. So when you start up the licensing it gives error message indicating this. Then you start up terminal server licensing on the sbsDC and all of you cals are gone. You have to add them all back into the system via MS Clearing House.
