New Trust Wizard Help

Welcome. Using this wizard, you can configure the appropriate trust type between this domain and any one of the following:

A Windows domain in this forest or in another forest. This requires either a forest trust, external trust, or, for faster user logon times within a forest, a shortcut trust.
A Windows NT 4.0 domain. This requires an external trust.
A Kerberos V5 realm trust. This requires a realm trust between certain domains that implement Kerberos V5.
Another forest. This requires a forest trust to allow resources to be shared between forests or an external trust if the domain is located in a separate forest.

The following table defines the trust options available in the New Trust Wizard and provides links to more information about each trust type. For more information about trust types, see Trust types.

Trust type	Transitivity	Direction	Description
External	Nontransitive	One-way or two-way	Use external trusts when users need access to resources located on a Windows NT 4.0 domain or on a domain located within a separate forest. This mechanism helps to provide backward compatibility with Windows NT environments and communications with domains located in other forests that are not joined by forest trusts. For more information, see To create an external trust and When to create an external trust.
Shortcut	Transitive	One-way or two-way	Use shortcut trusts to improve user logon times when made between two domains within a Windows Server 2003 forest. This is useful when two domains are separated by two domain trees. For more information, see To create a shortcut trust and When to create a shortcut trust.
Realm	Transitive or nontransitive	One-way or two-way	Use realm trusts to form a trust relationship between a non-Windows Kerberos realm and a Windows Server 2003 domain. This provides interoperability between Windows Server 2003 domains and any realm used in Kerberos V5 implementations. For more information, see To create a realm trust and When to create a realm trust.
Forest	Transitive	One-way or two-way	Use forest trusts to share resources from one forest to another. If a forest trust is two-way, it will effectively allow all authentication requests made in either forest to reach the other. For more information, see To create a forest trust and When to create a forest trust.
