I can create Standard and SCVMM environments by MTLM, but it doesn't work when I enable network isolation. MTLM displays the following error message: "TF259180: Team Foundation Server Could not find a network adapter in the VM".
If I go to SCVMM to see more details, I can see that one job "Create virtual machine" has failed. This shows the error: "Error (11427) The ownership for this object cannot be changed because the new owner is not a member of a user role that has access to this object"
In the properties of the virtual machine, I can see that the user role has not been changed and the internal network card has not been created.
I am sure the service account which is running the jobs is administrator in SCVMM and in the host where the machines are deployed.
All I know is that it worked before applying SP1 to SCVMM (upgrading hosts to Windows Server 2012) and Update 1 to TFS and Visual Studio.
