Hey TLG fans,
I have recently published the Test Lab Guide Mini-Module: Configuring a second SharePoint Server 2013 Preview farm. This new Test Lab Guide mini-module adds APP2 as a member of the corp.contoso.com domain on the Corpnet subnet and then installs SharePoint Server 2013 Preview as a separate farm that also uses SQL1 as its database server. With this configuration, you can build out and test SharePoint Server 2013 cross-farm scenarios.
Here is the resulting lab configuration:
The figure assumes a starting configuration of the Test Lab Guide: Configure SharePoint Server 2013 Preview in a Three-Tier Farm .
