If the WCM agent is unable to obtain a valid answer to DNS service record
lookup requests, it then attempts a DNS Hostname lookup.

protocol or port. Therefore, the retrieval module first uses the HTTPS on port
443. If this fails, the WCM agent then uses the HTTP on port 80. If the
lookup for host name WCM in the client’s domain fails, the WCM agent
then attempts to look for WCM for each sub-domain name. For example, if
the domain name is x.y.z, the WCM agent issues a DNS host name lookup
using the following names in the order shown until the DNS server returns a
