    Visited a site 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? :blink

    ah ha!

    existing servers 2003, new server 2003 r2! domain needs adprepping! :oops:

    but how would this affect the forest prep that was done as part of the exchange 2007 install? :blink

    Ooh, that's a good question! :ohmy One would hope that the R2 adprep stuff won't modify any of the schema classes and attributes created by the Exchange 2007 prep, but I don't know for sure. However, per this link, you should be fine to update the schema to R2.
