Best way to upgrade Exchane 5.5 on NT4 BDC to win2000 Member ServerHi Noam You cannot demote an NT4 BDC other than by completely rebuilding it. Therefore one option is to promote it to the PDC and then do an in-place upgrade to AD on the server in question. You could theoretically upgrade all the member servers first but this is not the MS recommended path. They suggest upgrading the PDC first hence why I would suggest promoting your BDC. Alternatively you could just upgrade the current PDC of course. Hope that helps. Don't heistate to get back to me if I can help further at all.
