Migration Issues Pertaining to Group Policy

  • Article

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.
