Note, you may be warned about Read-Only DCs - if you don't expect to have any, then you need not worry about it... and if you change your mind later, you can always run the ADPREP for read-only DCs later.

Hey there,<br />
<br />
I have a current server 2003 active directory domain setup with 5 DC's across myltiple physical locations, all tied together and replaicating fine<br />
<br />
I have a new server I am adding to the domain, it is a server 2008 unit. &nbsp;I went to DC promo the unit to the domain, and I got a message that i had to adprep /forestprep from the 2008 server tools CD on the 2003 before I could promote this unit to AD controller.<br />
<br />
What am in for during this process? &nbsp;Do I just go ahead and start doing adprep /forestprep on the other DC's one by one and it is pretty straight forward? &nbsp;What downtime will be expected? <br />
<br />
Thank you<br />
