The only thing I can think of to do is create a bat file that points to the VM in question that will auto start when a admin logs into the server.
The downfall to this is that if the server goes down for any reason then comes back up the VM won't start till someone logs in.
Is there a way to make VMware Player run as a service that will auto start with the server and load the corresponding VM?
I'm running the player on Server 2008R2
