I recently inherited a small network where the previous sysadmin had installed Windows 2003 Enterprise Edition on a server, and promoted it at some time to a Domain Controller. There are two other DCs in the network, several other 2003 member servers (of both the 32 and 64 bit varieties), and an Exchange 2007 server (which runs on a completely seperate 64 bit Win 2003 Std server, of course)
My DCs are getting old, and I recently thought to bring a newer server online and promote it to DC status. I created a new Windows 2003 Std R2 server, but when I attempt to dcpromo it I get an error that says the schema is incompatible (and to check adprep, forestprep, etc). Running those indicates the AD is already up to date. I surmise Im getting this error because the schema is in fact a 2003 Enterprise schema. To make matters worse, theres no indication Enterprise was ever bought, and instead I can find only a single "Promotional Sample, Not For Resale" box.
Is there any way to revert back to 2003 Std Schema (im guessing no)? Also, is my reading of the EULA correct in that the "promotional sample" server software was never legally licensed to run in a production environment?
