Why can't you install Exchange enterprise on Windows Standard? Sounds like you have other software on these machines as well that may be conflicting with your setup. It's not often that an Exchange server is installed on a DC, GC, FSMO holder etc. Often, it's on a standalone server instead. What errors occur in the event log at the same time?

You need to buy Enterprise edition of windows too.
