The OOB site server computer (by default, the Notification Server computer) must be registered in the DNS as ProvisionServer. Intel AMT computers send their Hello packets to this host name. If the OOB site server computer already has a name, other than ProvisionServer, add a CNAME (canonical name) record to the DNS. To do this with a Microsoft DNS server, open the MMC DNS branch, open the Forward Lookup Zones branch, right-click the entry for the Notification Server computer, and click New Alias. Then type ProvisionServer as the alias name. You must create a ProvisionServer entry for each DNS domain.

If you plan on installing multiple OOB site servers to different subnets or geographic locations, be sure that you configure DNS so that Intel AMT computers at each location contact their OOB site server computer.

See About OOB site servers.

After you install Out of Band Management Component, you can test if ProvisionServer resolves to the actual OOB site server computer.
