Forest Recovery Agent must be installed on the source computers. This is the same Forest Recovery Agent that is used by Recovery Manager for Active Directory Disaster Recovery Edition to recover domain controllers. Forest Recovery Agent also plays a vital part in the virtual test environment creation. For example, it is used to clean up metadata, seize FSMO roles, and validate that guest OS tools are installed on the virtual machines created in the lab.
For this reason, before creating a virtual test environment, you need to ensure that each source computer has the current Forest Recovery Agent version installed. To do so, you can use the Active Directory Virtual Lab console.
When you click the Verify Settings button in Step 4: Verify virtual machine creation settings in Step-by-step instructions, the Active Directory Virtual Lab checks and displays the Forest Recovery Agent version installed on the source computers in your project. If the current version of the agent is not installed, the Active Directory Virtual Lab displays a warning. If you ignore this warning, the current agent version will be automatically installed on the source computers during the virtual test environment creation.
Alternatively, you can use the Active Directory Virtual Lab console to manually install or update the Forest Recovery Agent: just select the appropriate shortcut menu command on the source computers in the virtual lab project.
This section describes how to open a legacy Virtual Lab Project (.vlproj) file created with the Active Directory Virtual Lab 8.5 if FIPS-compliant algorithms are enabled on the Active Directory Virtual Lab 8.6 or later computer.
The Active Directory Virtual Lab 8.5 uses hashing and encryption algorithms incompatible with FIPS. For this reason, to open a legacy .vlproj file created with the Active Directory Virtual Lab 8.5, you need to temporarily disable FIPS-compliant algorithms on the Active Directory Virtual Lab 8.6 or later computer.

Note: To protect its data, the Active Directory Virtual Lab 8.6 or later uses the SHA-1 hashing algorithm and the Triple DES encryption algorithm that are FIPS-compliant. For more information about FIPS-compliant algorithms, see Microsoft Knowledge Base article 811833 “The effects of enabling the ‘System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing’ security setting in Windows XP and in later versions of Windows” at http://support.microsoft.com.
