This topic applies to DNSSEC in Windows Server 2008 R2. DNSSEC support is greatly enhanced in Windows Server 2012. For more information, see DNSSEC in Windows Server 2012.

Use the following procedures to export a zone file and transfer it to a secure backup computer in preparation for signing the zone. This must only be done on the server that hosts the primary copy of the zone. If the zone is Active Directory integrated, you must first export the zone to a file. For file-backed zones, update the server data file before copying.

  1. Click Start, click Run, type dnsmgmt.msc and then press ENTER.

  2. In the DNS Manager console tree, right-click the name of the zone and then click Update Server Data File.

  3. Copy the zone file located in %windir%\System32\DNS from the secure signing computer to the secure backup computer.

  1. Open an elevated command prompt.

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

    dnscmd /ZoneExport <zone name> <zone file name>
    
  3. Copy the exported zone file from the %windir%\System32\DNS directory on the secure signing computer to the secure backup computer.
