Upon further inspection, I see that I can disable or deactivate
classes and attributes in the Active Directory Schema snap-in. Is
this an advisable thing to try?

Apparently at one time, an attempted Exchange install had been performed, or
at least a "setup /forestprep" was run at one point in preparation for
Exchange.

To verify that, create an MMC and add the ADSI Edit snapin and take a look
at the Schema Container. When you click on the Schema object in the left
window pane, you will find on the top of the right results pane an object
counter. If Exchange was installed, it will report about 2200 objects. If
not, it's only about 1100 or so. I can't remember the exact numbers, but
there are about 1000 Exchange objects and if it is over 2000, it is a
definite sign that an Exchange forestprep was run at one time.

btw- to get the ADSI Edit snapin, install the Support Tools (free on the
Windows CD).

If this is the case, the way to fix it is to follow this article below. It's
really not that hard, but one thing I need to mention is that you CAN'T just
simply dectivate the objects because their attribute object IDs are needed
in order to renamed for Windows 2003.

Windows Server 2003 adprep /forestprep command causes mangled attributes in
Windows 2000 forests that contain Exchange 2000 servers:

If you have difficulty following the procedure, you can also call Microsoft
PSS. I believe their charges for support are about $250.00 USD per incident
(unless it went up) and they will take as long as is required to fix it for
you.
