Hey TLG fans,
I have published the Test Lab Guide Mini-Module: Creating a second forest and domain. This new Test Lab Guide mini-module adds DC2 as a domain controller for the hr.contoso.com AD DS forest and domain on the Corpnet subnet. There is no trust relationships between this new forest and the existing corp.contoso.com forest. In this configuration, you can build out and test untrusted cross-forest/domain scenarios. Alternately, you can configure a trust between them and test trusted cross-forest/domain scenarios.
Here is the resulting lab configuration:
The figure assumes a starting configuration of the Base Configuration. However, this mini-module can be added just about anywhere in a stack as it does not depend on any existing servers.
