unable to add an additional dc
Visited a school today which is having a strange problem, they have an existing domain with with their 2 dc's running win 2003. They also have a member server which runs exchange 2007.
Their 3rd dc died the other day and they have restored it effectively as a new server with a new name, however when they come to dcpromo the server they get the following error:
"active directory installation cannot continue because the forest in not prepared for installing win 2003. use adprep to prepare both the forest and the domain."
now i know that the domain is at the right level because they have existing 2003 dc's, what I also know is that when they installed exchange 2007 they had to forest prep the domain to accomodate it.
anyone got any ideas?
