OWA 5.5

By david ·
Here is the situation:
We were a NT 4.0 shop, Exchange 5.5 using OWA, we started a Windows 2000 migration. We migrated all our NT 4.0 DC's to Windows 2000 except one. Of course we are in mixed mode.

Just some back ground: Our OWA computer got hit by the code red. Rebuilt it, no problem. Since then we have migrated our last NT 4.0 DC to Windows 2000. We have not moved to native mode yet.

Problem: Since we were hit by the virus and the OWA was on our domain, we wanted to move it theour DMZ. Built new computer, put it in the DMZ but when we start the setup for Exchange 5.5 we get the error "This computer must belong to a Windows NT domain before Exchange Server can be installed" Ok no problem we can move it back to our domainthen make it a part of the domain then move it back to the DMZ. We got the same error. Ok. I will but it back in the domain and install the softeware then move it back. Same error. Am I getting this error because we have no Windows NT 4.0 DC'sanymore? What can I do to fix this? If our exsisting OWA crashes we will not be able to get it reloaded because we have no NT 4.0 DC's?

Any ideas?
Thanks,
David

Mixed vs Native only affects DC's. Once you switch to Native you can no longer join NT4 BDC's to the domain. NT4 server can join as member servers to any type of AD domain mixed or native.
Okay to your question: The computer OWA is running on must be part of your NT domain or a trusted domain. The reason is authentication. OWA has to authenticate users to their mailboxes. ie must belong to the domain security model.
