Where do you see workgroup being the best solution here?
This needs to be setup correctly. Running DCPromo is like saying point and click. Where else did you plan to take him? Or were you going to leave it with that brilliant "technically and correctly answered" response and leave him to the wolves when the workgroup grinds to a halt?
He should demote the server, then promote it correctly, creating a new domain, simply because it will erase what the last dude did to the server, and allow him to build on this from scratch, add a second server, and promote that one to a DC. Then migrate the PC’s to the new domain. End of story. I am not taking credit for any of my aanswers, as I know to do it that way would take some work, and I am certainly not going to spoon feed all of the steps.
Sorry Bob T, I hate being this blunt with you, being that you are new here. But I have to call it like I see it. Feel free to take all of this with a grain of salt.
