I tried the MS method earlier this morning. I ran forestprep, but it wouldn't proceed because ADC wasn't installed. So, I installed ADC (didn't create a connector, just installed the service) and now forestprep runs.
So, it would appear the correct route is: install ADC, forestprep, create an ADC connector, run domain prep, upgrade. --Jon Jon Farr Server Administrator Computers in Ministry List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
