Traffic Manager - Internal DNS

$

I've been testing Traffic Manager with Site Recovery using the failover method for a web server. It's working well and doing what it's supposed to do when the primary sever goes down and accepts web requests once it fails over to the Azure instance.

Here is my question. There is another server that looks at a file share on this azure server for it's licensing. (ex.\\azureserver\license\)

When the server is failed over in Azure, this other machine cannot resolve "azureserver" to it's internal IP, as it's resolving it to the traffic managers public DNS name, which in turn points to the public DNS name of the "azureserver" instance. If I point the other server to the " azureserver" internal IP, all is well, however, I don't want to have to do that in the event of a disaster.

What am I missing here to allow other machines to resolve the "azureserver" to it's internal IP in this case?

(Note: Obviously cannot add an A record in internal DNS to "azureserver" because there is a CNAME record for that name pointing to the Traffic Manager DNS Name)
