Upgrading Windows 2003 domain to 2008 R2. Did clean install of R2 on new server; Ran ADPREP forestprep and domainprep on existing 2003 server OK. added new server to existing domain OK too.
Attempted to elevate new R2 server to DC with DCPROMO. Being stopped with message that DCPROMO no-can-do because something (don't recall what at the moment, but I think the new R2 server) is not in "native mode" Can't find out what that "native mode" blockage is all about.
Any clues / leads / suggestions / solutions most welcome.
Thanks, Ron Hicks
