Refers to the client software that is used to talk to a DNS server, such as DNSd, and hence, translate Internet names into IP addresses. Since resolvers do not know the location or IP address of any DNS servers, let alone which servers they should talk to, the resolver's configuration parameters are critically important. An incorrectly configured resolver can prevent clients from getting Internet name resolution, and hence, from accomplishing any Internet-related work. The resolver on the Raptor Firewall, like all Windows NT 4.0 systems, is set in the DNS Search Order field found in Start> Settings> Networks> Protocols> Tcpip properties> DNS tab.
