    Hi!
    The answer is yes!

    In my research, lyncdiscover. <domain> should be an A record pointing to the IP address of the external web services which is normally an ISA reverse Proxy. This record should also only exist externally. Lyncdiscoverinternal.<domain> should be a CNAME or A record to the Front End Server and only exist on the internal network.
