Hi! I am trying desperately to extend my schema in windows 2000 to accomodate exchange. I am running exchange server on an additional domain controller and not on the root domain controller. I have couple of child domain controllers connected to the root via 64k lesased lines on which i have to configure mail. I do not wish to install exchange 2000 on the child domain controllers. I ran the forestprep on the exchange server(additional domain controller) and when I ran the domainprep immediately after, it says that the forestprep has not yet run and that I have to run forestprep first,,,, which I have already done. Is there a problem??? Can i go ahed and install exchange without running forestprep?? On a test which i conducted using switches the forestprep ran very well. Does it take time for forestprep to settle down?? I am confused!
