Problem

You want to modify the DNS Server settings.

Solution

Using a graphical user interface

Using a command-line interface

With the following command, replace <Setting> with the name of the setting to modify and <Value> with the value to set:

	> dnscmd <DNSServerName> /config /<Setting> <Value>

The following command enables the EnableDnsSec setting on dns01:

	> dnscmd dns01 /config /EnableDnsSec 1

The following command disables the NoTcp setting on the local host:

	> dnscmd /config /NoTcp 0

The following command sets the DsPollingInterval setting to 60 on dns02:

	> dnscmd dns02 /config /DsPollingInterval 60

For the complete list of settings, run dnscmd /config from the command-line.

Using VBScript

	set objDNS = GetObject("winMgmts:root\MicrosoftDNS")
	set objDNSServer = objDNS.Get("MicrosoftDNS_Server.Name="".""")
	objDNSServer.<Setting> = <Value> ' e.g. objDNSServer.AllowUpdate = TRUE
	objDNSServer.Put_

Discussion

The Microsoft DNS server supports a variety of settings to configure everything from scavenging and forwarders to logging. With the DNS Management snap-in, the settings are spread over several tabs in the Properties property page. You can get a list of these settings by simply running dnscmd /config from a command line. For the CLI and VBScript solutions, the setting names are nearly identical. In the VBScript solution, be sure to call the Put_ method after you are done configuring settings in order for the changes to take effect.
