Our office recently switched from a Windows NT 4.0 server to a Windows 2000 Server. Upon the switch to the new server the company that set it up configured it with no active directory. In doing this, our company realized that when the employees log on the the network it doesn’t ask you to change your password after it expires as it did on our Windows NT Server. We want the security of making the employees change their password ever so often. The company is now wanting to switch the server from no active directory to active directory and have nominated me to do this task. My question is: what is the procedure for this? What kind of network downtime do you think I am looking at and what are some of the complications I might face when doing this? Thank you in advance for any help you may provide.
