Important Information

It is required that a Windows server reboot during the make managed process. If the server already exists and is being converted then the server should be placed in maintenance mode prior to running the blueprint and removed from maintenance mode once an email verifying completion has been received.

The following is not meant to be a complete description of everything that happens when a VM is prepared for management, but to give users a better idea of configuration changes that might be necessary to manage their servers.

Many of the following items are mandatory. Some default items have options for change. If you would like to alter default options, please contact the CenturyLink Client Service Center at 1-888-638-6771 to submit your request for review.

  • A client is downloaded onto the VM. This client allows for installation of management tools, configuration, and remote support.
  • If a dedicated domain exists for the customer, the server will be joined to it. Otherwise, the server will join a shared domain.
  • Our monitoring agent is installed and configured. Heartbeat monitoring of the agent commences.

  • 10 GB D: drive is added. If D: drive already exists, the next available, unused drive will be added.
