• Verify that the Hyper-V or VMware ESX/ESXi server is running.
• Ensure that the virtual server has access to the network and is visible to/accessible from the host machine (if it is running on a different computer).
• If you are using VMware and you received XE values 22002 (55F2) or 22003 (55F3), verify that the VMware vSphere API is installed. See VMware vSphere API Requirement on the AdminStudio Machine.
