Modify the DNS Server Search Order for a Network Adapter

Configures a TCP/IP-bound network adapter to use two DNS servers: 192.168.1.100 and 192.168.1.200. Note that even if a computer only uses one DNS server, the IP address of that server must still be passed to the SetDNSServerSearchOrder method as an array (in that case, an array with only one element).
