Introduction to Domain and Forest Trusts

By using Windows Server 2003 domain and forest trusts, service administrators can create or extend collaborative relationships between two or more domains or forests. Windows Server 2003 domains and forests can also trust Kerberos realms and other Windows Server 2003 forests, as well as Microsoft Windows® 2000 domains and Windows NT® 4.0 domains.

When a trust exists between two domains, the authentication mechanisms for each domain trust the authentications coming from the other domain. Trusts help to provide controlled access to shared resources in a resource domain (the trusting domain) by verifying that incoming authentication requests come from a trusted authority (the trusted domain). In this way, trusts act as bridges that allow only validated authentication requests to travel between domains.

How a specific trust passes authentication requests depends on how it is configured. Trust relationships can be one-way, providing access from the trusted domain to resources in the trusting domain, or two-way, providing access from each domain to resources in the other domain. Trusts are also either nontransitive, in which case a trust exists only between the two trust partner domains, or transitive, in which case a trust automatically extends to any other domains that either of the partners trusts.

In some cases, trust relationships are established automatically when domains are created; in other cases, administrators must choose a type of trust and explicitly establish the appropriate relationships. The specific types of trusts that are used and the structure of the resulting trust relationships in a given trust implementation depend on such factors as how Active Directory is organized and whether different versions of Windows coexist on the network.

Method #2: Use a Script

You can create a WMI script that changes the volume licensing product key, and then deploy this script in a startup script. The sample ChangeVLKey2600.vbs script and the sample ChangeVLKeySP1 script that are described in this section use the new volume licensing key that you want to enter, in its five-part alphanumeric form, as a single argument. Microsoft recommends that you use the ChangeVLKey2600.vbs script on Windows XP-based computers that are not running SP1 and that you use the ChangeVLKeySP1.vbs script on Windows XP-based computers that are running SP1. These scripts perform the following functions:

  1. They remove the hyphen characters (-) from the five-part alphanumeric product key.

  2. They create an instance of the win32_WindowsProductActivation class.
    They call the SetProductKey method with the new volume licensing product key.

You can create a batch file or a CMD file that uses either of the following sample scripts, together with the new product key as an argument, and either deploy it as part of a startup script or run it from the command line to change the product key on a single computer.

ChangeVLKeySP1.vbs

ChangeVLKey2600.vbs

Example

The following example describes how to use the ChangeVLKeySP1.vbs script from a command line:

  1. Click Start, and then click Run.

  2. In the Open box, type the following command, where AB123-123AB-AB123-123AB-AB123 is the new product key that you want to use, and then click OK:
