I think the offical word is backup the meta data, backup something else and then do a system backup. Do a clean install and restore data. Wonder if a mirrored drive would work?

If you want to maintain your domain but reinstall on the OS on that server than by far the easiest thing to do would be to get your hands on another pc. Install 2003, promote it to be a dc. It will replicate all the AD data. Demote the current server, format it, reinstall the OS, promote it to be a dc and you can then demote the other pc and you'll be all set.
