Ad Site specific DNS response

Question

_{Tuesday, November 13, 2018 5:48 PM}

We need to create a service record for Jabber that will return a different IP based on which AD site the user is located.

_cisco-uds._tcp.internal.domain

I've tried creating the record _cisco-uds within the _tcp containers in the different sites, different DNSDomain sites and different DNSForest sites to no avail. 

Is it possible to have AD DNS return a different IP for a service record based on the AD site the workstation is located?

Hello,

With DNS policy you will be able to kind of achieve what you want, it will not really be based on AD Site but on subnet like Eric is saying (If your design is good normally each of your AD site got a subnet attached to it).

DNS polices is server based and not replicated so if you don't control which DNS they will use, you will have to configure it on each DNS server.

Last but not least as you saw in the link of Eric DNS policies is a new feature of Windows server 2016, so if you have 2008 or 2012 DNS they won't be able to use that feature.

Best Regards,

Hi,

Thanks for your question.

Unfortunately, according to DNS policy, your requirement may not be realized.

You can use  DNS policy to realize traffic management based on geo-location.

You can refer to:

Do all DNS servers have to be on Server 2016 for this however?

Hi,

Thanks for your reply.

DNS policy is a new in Windows Server 2016.You can use DNS Policy for Geo-Location based traffic management, intelligent DNS responses based on the time of day, to manage a single DNS server configured for split-brain deployment, applying filters on DNS queries, and more.

I guess the question is more that we have 6 DNS servers and only 1 is 2016.  So I assume that if a client is talking to a 2008 or 2012 DNS server that the DNS policies would not be in affect?
