Recently migrated from Active Directory integrated DNS to Bind DNS. This was a complete transition and all works excellent, except....
We have multiple sites and some domain name lookup requests are being resolved to a domain controller in a different site instead of the closest server based on Round Robin. We have 3 domain controllers with 1 in a VPN connected site.
Example: user is SiteA does a lookup for domainname.com, the first address returned is for the DC in SiteB. Depending on what is making the request, the user is then connected to SiteB for the session causing a performance degradation. This is evident in DFS (Distributed File System) connections.
Microsoft DNS had a feature of netmask ordering to be able to manage the response depending on where the user was that was asking.
Is there a way to control this functionality in BIND 9?
