I will post my question here because it is specifically about Lync.

 

Rusty, did you add static hosts for all your Lync addresses?

 

I am using this document for Lync access. https://technet.microsoft.com/en-us/library/gg398758.aspx

 

I am testing only with the internal records in the list, but I believe the Lync client caches the SVR record _sipinternaltls._tcp.domain address and keeps using it.

 

I do not want to block the internal IPs of the Lync servers, as I need RDP access to them over VPN, and dont want to RDP to another server to then RDP to the Lync servers.

I have this corrected "I believe" The Lync Client Configuration Information shows the inside user status as false now. we have split-brain DNS I have added the following static hosts to the Network Access List in the access policy lyncdiscoverinternal. - set to 1.1.1.1 so it times out _sipinternaltls._tcp. - set to 1.1.1.1 so it times out sip. - set to external IP I also have other external DNS records in there. not sure if they are needed or not. I believe the sip. was the key as that is resolved from the SVR records for _sip._tls. maybe someone else can chime in to verify the proper records to have.
