Hi, we have an old windows 2000 server running 5.5 sp4. We have about 100 users. I want to install 2000 on a new server and eventually move all mail etc from the old to the new server. I was told to run "setup /forestprep /domainprep" on one of our domain controllers. I did this last week but it is not obvious if it has worked. 1) How do I check to see if it has worked? 2) On reading various articles the subject of an Active Directory Connector (ADC) has now emerged. Should I have installed this first? If so how can I get round this now.
