Modifying the DNS Server Configuration






Modifying the DNS Server Configuration

Problem

You want to modify the DNS Server settings.

Solution

Using a graphical user interface
  1. Open the DNS Management snap-in.

  2. If an entry for the DNS server you want to connect to does not exist, right-click on DNS in the left pane and select "Connect to DNS Server." Select "This computer" or "The following computer," then enter the server you want to connect to (if applicable) and click OK.

  3. Right-click on the server and select Properties.

  4. There will be several tabs you can choose from to edit the server settings.

  5. Click OK to commit the changes after you've completed your modifications.

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.
