Good morning all, we're working on some in house projects and hit a snag.
Existing environment consists of a Server Standard 2003 R2 x64 acting as our one and only primary DC, also hosts Exchange 2007. We're trying to attach a Server 2008 R2 x64 to the domain. Of course, when I run dcpromo it kicks and tells me to run adprep, which makes sense. However, when I run adprep (either forestprep or domainprep), it returns the same 0x3a error message.
I'm a little lost - I've done this before and it worked smoothly, not sure what I've done to break it this time! Thanks.
