Recently at my company we did a migration from NT --> AD 2003 Native at the
forest level. I am not experiencing replication issues. However, the problem
(or is this really a problem) is that all five of my domain controllers have
the same SID!

- what problem could this cause
- how is this possible anyway
- would this require rebuilding all servers

Can someone please explain to me why this is possible, because I am
wondering if I am experiencing issues that I am unaware. Please advise...

it sounds like the servers were imaged, if not this time then when NT was installed. there is a free program called new sid from sysinternals that will create a new sid and make all necessary changes for you. I have used it on XP without problems. I don't know if it will work on a server or if there are possible problems if you use it on a server. Sorry I can't give you an answer but I will be watching this to see what the experts have to say.
