Hello Geeks i am having a problem setting up my  IFD,  i have created all the necessary sub-domains in the DNS like adfs, sts1, crm, auth, internalcrm and so on, but when configuring the IFD i got an error message that my external domain is not accessible which is auth.mydomain.com:444. Please any help will be appreciated. Or better still if someone can give me a guide of configurng IFD in Dynamics  CRM 2016. I am using a windows server 2012 and ADFS 3.0, I will be glad if someone can come to my rescue ASAP because i have been banging my head through this thing.

Regards,

Olamilekan Bello.
