Restrict Zone Transfers

Published: October 7, 2009

Updated: October 7, 2009

Applies To: Windows Server 2008 R2

Use the following procedure to specify IP addresses that are allowed to receive a zone transfer. By default, zone transfers are disabled for zones that are AD integrated. For non-AD integrated zones, default settings allow zone transfers only to servers that are listed on the Name Servers tab. For increased security, disable all zone transfers unless they are required. If required, configure this setting to allow zone transfers only to specified IP addresses.

noteNote
If you allow zone transfers to any server, all resource records in the zone are viewable by any host that can contact your DNS server.

Membership in the Administrators group, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).

  1. Click Start, click Run, type dnsmgmt.msc, and then press ENTER. The DNS Manager console will open.

  2. In the console tree, click the name of the DNS server you wish to configure, and then open Forward Lookup Zones or Reverse Lookup Zones.

  3. Right-click the name of the zone you wish to configure, and then click Properties.

  4. On the Zone Transfers tab, do one of the following:

    • To disable zone transfers, clear the Allow zone transfers check box and the click OK.

    • To allow zone transfers, select the Allow zone transfers check box, and then do one of the following:

      • To allow zone transfers to any server, select To any server and then click OK.

      • To allow zone transfers only to the DNS servers that are listed on the Name Servers tab, select Only to servers listed on the Name Servers tab and then click OK.

      • To allow zone transfers only to specific DNS servers, select Only to the following servers, add the IP address of one or more DNS servers, and then click OK.

  1. Open an elevated command prompt.

  2. Type the following command, and then press ENTER:

    dnscmd <ServerName> /ZoneResetSecondaries <ZoneName> {/NoXfr | /NonSecure | /SecureNs | /SecureList [<SecondaryIPAddress...>]}
