Windows 2000 domain with 3-4 domain controllers, two exchange 2000 clusters in two different physical offices.
3 office locations
the windows 200 domain has two domains due to the different companies under the one forest.
the primary tasks is to buy new 2003 R2 servers, make them DCs, two in the primary office and one in each of the others
make the first of them the new primary DC , global catalog etc...
i know you have to prep the forest and then domains
but my only concern is what if any impact this will have on the existing exchange clusters?
or should all the prep tasks have to be done both in succession and on same day ,,, in other words can i just forest prep on a friday evening, then domain prep the domain that office uses and leave the 2nd domain in the forest for the next weekend.
are there other thing s i need to take into consideration?
