I have three single-label domains. By single lable, I mean my domains names are simply domain1, domain2 and domain3. There is not .com or anything like that.
Anyway, I am trying to use the ADMT to migrate users from one domain to another and domain1 cannot see domain2 or domain3.
I am asking what I must do to my DNS in order for these three single lable domains to see each other?
