Cname records for Auto-discovery

If you want add Windows Device (Windows Phone 8.1/10 or Windows PC 8.1/10) on the intune platform, you need add cname records on your Public DNS Server. This operation is needed to operate the auto-discovery with the Windows devices only. There is no problem with IOS and Android Device.

For the connection, the user enter a corporate email (the UPN – User Principal Name). After authentification, the device tries to auto-discover the server and start the enrollment process.

If you not add a CNAME, the device enrollment server won’t be found and you need enter the server address. The old address is manage.microsoft.com, it is now necessary to use enrollment.manage.microsoft.com.

Configure auto-discover

If you want configure auto-discover of the enrollment server, you need create one cname records.

Cname : EnterpriseEnrollment.company_domain.com
points to EnterpriseEnrollment-s.manage.microsoft.com
TTL : 1 hour

change the company_domain.com by your registered domain name. For example, if i use inyourcloud.fr the value of the CNAME is EnterpriseEnrollment.inyourcloud.fr.

If you use two or more domain, you need create two or more CNAME. For example, if i use the domain inyourcloud.fr and nibonnet.fr i need create :

Cname : EnterpriseEnrollment.inyourcloud.fr
points to EnterpriseEnrollment-s.manage.microsoft.com
TTL : 1 hour

Cname : EnterpriseEnrollment.nibonnet.fr
points to EnterpriseEnrollment-s.manage.microsoft.com
TTL : 1 hour
