Hi!

I have FE, Edge, RP

I am trying to deploy SFB Mobility.

My internal and external domain names are different.

Question: do I need to remove (lyncdisocverinternal.externaldomain.com ) from internal DNS record or what is the correct way?

    @JulieMardersdw214 ,

    Question: do I need to remove (lyncdisocverinternal.externaldomain.com ) from internal DNS record or what is the correct way?

    No, you don’t. During DNS lookup, a connection's attempted to the FQDN that's associated with the internal DNS record (lyncdiscoverinternal.[internal domain name]). If the internal DNS record can't be used to make that connection, a second connection is attempted, this time to the external DNS record (lyncdiscover.[sipdomain]).

    For more information, please refer to this article.
