Setting Network Connections Options via Registry or Scripting

In Windows XP SP2
If I Click Start, click Control Panel, and then double-click Network Connections.
In Network Connections, right-click Local Area Connection, and then click Properties.
In Local Area Network Connection Properties, click Internet Protocol (TCP/IP), and then click Properties.
In Internet Protocol (TCP/IP) Properties, click Advanced, and then click the DNS tab.
There are two options at the bottom of the dialog box.
Register this connection’s addresses in DNS
Use this connection’s DNS suffix in DNS registration
Is there any way to set these two options with Registry entries or by scripting ?
