Network Isolation and Domain Joined Machines


If you decide to build an environment in Lab Manager which has a server performing the domain controller role, when you are joining the machines to the domain make sure you don’t rename them.  If you do you will get “Additional Information” messages displayed about the state of those machines.

Environment Messages

Network isolation is complete. Additional information is available for one or more machines.

TF259576:Team Foundation Server could not determine if this machine is joined to a domain or a workgroup. OS failure code: 0x54B. To safely clone the environment, ensure that this machine is not joined to a domain controller outside the environment.
