The Active Directory Migration Tool provides an easy, secure, and fast way to migrate to Windows 2000 Active Directory service. As a system administrator, you can use this tool to diagnose any possible problems before starting migration operations to Windows 2000 Server Active Directory.

You can use the task-based wizard to:

• Migrate users, groups, and computers.
• Set correct file permissions.
• Migrate Microsoft Exchange Server mailboxes.

The tool's reporting feature allows you to assess the impact of the migration, both before and after move operations. In many cases, if there is a problem, you can use the rollback features to restore previous structures automatically. The tool also provides support for parallel domains, so you can maintain your existing Windows NT 4.0 domains while you deploy Windows 2000.

• Target domain. ADMT can run on any computer that is capable of running the Windows 2000 Server operating system.
• Source domain. The source domain must be running either Windows 2000 or Windows NT 4.0.

The primary domain controller (PDC) of a Windows NT 4.0 source domain must have SP4 or higher installed. The ADMT agent (installed by ADMT on the source computers) can operate on computers running Windows NT 3.51 (with SP5); Windows NT 4.0 (with SP4 or higher); or Windows 2000.

1. Go to the location where you saved the file and double-click admt.exe.
2. Click Remove All in the Setup Wizard.
