Not sure what ADMT is? Here is the description of ADMT 3.0:
The Active Directory Migration Tool version 3 (ADMT v3) simplifies the process of restructuring your operating environment to meet the needs of your organization. You can use ADMT v3 to migrate users, groups, and computers from Microsoft® Windows NT® 4.0 domains to Active Directory® directory service domains; between Active Directory domains in different forests (interforest migration); and between Active Directory domains in the same forest (intraforest migration). ADMT v3 also performs security translation from Windows NT 4.0 domains to Active Directory domains and between Active Directory domains in different forests.

Mostly of interest to tech support people and debuggers, but there is a known issue with the shipping kernel of Windows 2008 that in certain cases, does not include system page directory information in the dump file it creates during a crash. Most people won't be interested/need this update, but for those tracing problematic system issues, it can be an important omission.
