Migration Issues Pertaining to Group Policy
In organizations containing many networked Windows NT 4.0–based computers, including primary domain controllers backup domain controllers, client workstations, and client stand-alone servers, it might not be practical to upgrade all computers simultaneously to Windows 2000. Therefore, when a network of Windows NT 4.0–based computers is upgraded to Windows 2000, you need to know what to expect during and after the migration process.
Before the migration is complete you might need to manage a domain in which all of the following types of computers participate:
Windows 2000 Server domain controllers
Windows NT 4.0 Server domain controllers
Windows 2000 Professional clients
Windows 2000 Server clients
Windows NT 4.0 Workstation clients
Windows NT 4.0 Server clients
Computers running earlier versions of Windows, such as Windows 98
There are many interactions to consider. Fortunately, the conditions on the client side are not complicated.
