Doing so enables you to establish priority groupings and weighting within each group, which specifies the order in which to use KMS host computers and balances traffic among multiple KMS host computers. You can add priority and weight parameters to the DnsDomainPublishList registry value for KMS host computers. This enables advertisement of SRV RRs for KMS in one DNS server and KMS clients that have other primary DNS servers to find it. The address of a DNS server that contains the SRV RRs can be listed as a suffixed entry on KMS clients. The first time that a KMS client queries DNS for KMS information, it randomly selects a KMS host computer from the list of SRV RRs that DNS returns. How DNS is used to find a KMS host computer Set the permissions on the DNS server to enable updates by members of the newly created security group.įor more information, see Configuring DNS.Add each computer running KMS to the new security group.Create a global security group in AD DS for the computers running KMS.Ensure that all computers running KMS are members of the same Active Directory Domain Services (AD DS) domain.If there is more than one computer running KMS, subsequent KMS host computers cannot change or update SRV RRs unless the permissions on the DNS server are configured to allow this.Ĭhanging the permissions on the DNS server requires administrative rights in the domain.

But, only the first KMS host computer can create an SRV RR. The KMS host computer automatically publishes its existence by creating service (SRV) resource records (RRs) on the DNS server. To activate volume licensed versions of Office, including Project and Visio, by using Key Management Service (KMS), the KMS host computer for Office must be discoverable. Applies to: Volume licensed versions of Office LTSC 2021, Office 2019, and Office 2016 (including Project and Visio)
