Maybe I should start over and tell you the steps that I've taken. This is a brand new installation:

Install Windows 2000 Server on NTFS partition
Use DCPROMO to install Active Directory
Active Directory installs DNS and adds forward and reverse lookup zones
Use the network identification wizard on a Windows 2000 Professional to:
- specify this machine as part of a business network
- specifiy my company uses a network with a domain
- supply the wizard with the administrator's username/password and domain

When I do all of this, the system says that it cannot find an account for my computer of the specified domain. It asks me for the computer name and domain. I specify the name of my Professional machine as well as the domain I am trying to join.

This is where I get stuck. Any ideas?
