Switching to Native Mode

I would like to switch from W2K Mixed mode to Native mode, but still have one remaining NT4 Server that is a domain controller. Am I safe to do this with the assumption that the NT4 domain controller will simply be ignored for authentication services, or will this casue problems? Basically, I don't want to spend the money on a W2K license as this machine will be de-commissioned within a year. Thanks!

If the remaining NT 4 server is a domain controller don't do it.  If it is a member server, then go ahead.

It will cause problems.  You need to rebuild this server if it is a domain controller and make it a member server.  Unfortunately dcpromo is not available in NT 4 and to quote MS:

"Microsoft Windows NT Server 4.0 does not permit the demotion of a backup domain controller to a member server."

OK, thanks for the info...how about this then:

Remove the NT4 BDC, promote it to a PDC, change the domain name and reattach to the network.

Setup a trust between the W2K Native Mode domain and the newly named NT4 domain?

I don't have many resources to modify permissions on so it wouldn't be a big hassle from that perspective.

I don't uderstand why you don't want to run in mixed mode until you retire that box?  You make it sound simple, but what your proposing is pretty complex, trusts in NT work much differently than 2000 trusts.

It's a long story, but we're adding a 2000 exchange server and from everything we've read, the domain must be in native mode.

This is true.  Exchange 2000 is basically an E-Mail enabled Active Directory.  

Is figuring this out worth the man hours and overhead implementing a mixed environment?  Worth it compared the cost of one more server license?  There are no payroll taxes or benefits associated with a license.  How many other projects could you be working on if you did not have this obstacle in your way, for one you could get this done the right way rather then ending up with some band-aid.  IMHO it is not worth the cost of one license to mess around with this, just ask your accountant.

For this situation, changing the NT4 server to another domain worked perfectly. Thanks for your input MSGeek.
