to clarify, this sounds kind of like you are running exchange on the PDC?

you can't demote an NT4 PDC to a stand alone or member server, it
requires a re-install.

I have done exchange 5.5 server migrations in the past, it's not too
difficult.  setup a new member nt4 server, install exchange on it and
join the existing (what's it called?  domain, cluster, group,
something) and then you can move connectors and  public folders and
mailboxes to the new one.

Also, has upgrading exchange or migrating to something else been
considered, like zimbra or Kerio (which is what i use now) that's
still Outlook friendly but more flexible?  Kerio can even be setup to
auth to PAM, so you can switch out how it auths by switching up the
PAM config.
