I know this will be a very elementary question, but I just wanted to run it by the experts to make sure I'm not missing anything.
I finished testing on my test domain for adding 2008R2 servers to my 03 domain. In that test I had servers that had DVD roms, so I could do the adprep on the 03 DC no problem. In my production environment, my 03 servers do NOT have DVD roms. What I have done so far is copied the 08R2 disk contents to a folder on the D drive of my 03 DC that holds all of the FSMO roles. Can I just do the adprep from that directory on the D drive or do I have to run it from the DVD?
I'm pretty sure I can run it from the D drive, but just watned to make sure I wasn't missing anything.
