IIS Domain Change?

Hi

We are working on a large environment and are still in the process of
migrating our NT4 servers to Windows 2000/2003. AD is up and running, but
authetication is still done though the old NT4 PDCs/BDCs of the many domains.

It has been decided to go into one big AD domain, SLI.BZ.

Now, what would I need to verify to actually make sure my IIS servers are
changed from their old NT4 domain to the new AD domain?

My list includes this so far:
- Anonymous user access to the many sites on IIS
- DCOM configuration for NT4 domain user security
- Certificate servers (will I need to make new certificates?)
- Scheduled tasks
- Services running from a user context in NT4 domains

Is there a guide for IIS migration from NT4 domains to AD domains? Any tips,
things to make sure to backup first, things that always fail and that will
need special care?

Thank you very much
