I have active Directory installed on three domain controllers spread over three sites, linked by permanent VPN connections. However I have noticed that in the dns snapin only two of these sites are listed in the sites container for my domain. I haven't encountered any problems and everything looks correct in Active Directory Sites and Services.
Does anyone know if this is going to cause problems for this site and if so what is the safest way to correct it.
To clarify - I have 3 active directory domain controllers which are each a site, all are dns servers, no errors in the event logs on all 3 servers. This setup has been running for several months with no noticable problems. DNS is the same on all three sites in the snap-in.
