Resource Record type
We need to understand below things before creating any SRV record for any service or application, Like Exchange or KMS services.

Service: This is a symbolic name for the service, such as _sip, and must begin with an underscore (_).

Protocol: The transport protocol of the service that must begin with an underscore (_). This is most commonly entered as _tcp or _udp.

Name: The hostname or prefix of the record, without the domain name. Enter @ to put the record on your root domain, or enter a prefix, such as mail or phone.

Value: The hostname of the machine providing the service, such as mail.coolexample.com.

Priority: The priority determines which record to contact first when multiple SRV records with the same Name exist on the domain. A lower number means more preferred, and the record with the lowest priority will be used first.

Weight: The relative weight for SRV records with the same priority. A higher value means a higher chance of getting picked.

Port: The port where the service can be found, such as 80 or 21.

TTL (Time to Live): The amount of time the server should cache information before refreshing. The default setting is 1 hour.

To create SRV record for exchange autodiscover, enter the following details and click OK.

  • Service—_autodiscover
  • Protocol—_tcp
  • Port number—443
  • Host offering this service—mai.windowstechno.local
