In the DNS service record lookup, an administrator can configure the DNS server to provide the server and port number for a service that is referred to as _WCM._tcp. Multiple configuration repository server/port values can be provided. The WCM agent accesses them in order, according to the weight and priority associated with each entry.

Since the DNS server may not supply a protocol string associated with each server/port entry, the WCM agent determines the protocol based on the port specified. For example, if port 80 is specified, the WCM agent determines that the protocol being used is HTTP. If the DNS service record lookup for _WCM._tcp <full domain> fails, the WCM agent attempts _WCM._tcp <sub-domain>and so on upon further failures. For example, if the domain name is x.y.z, the WCM agent issues a DNS service location lookup using the following names in the order shown until the DNS server returns a valid answer:

1_ WCM._tcp.x.y.z

2_ WCM._tcp.y.z

3_ WCM._tcp.z
