Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I have a Windows 2008 R2 Server, Its primary role is to be a DNS server.

I cant find how to import the previously "exported" DNS entries.

To export I selected the server, clicked on Action->Export List.

This created a text file of the entries. How do you import these entries if something was to go wrong and I needed to restore the previous settings ?

If there is a way to do this via GUI that would be preferable to me.

Is this a standard zone or an AD-integrated zone? –  Massimo Sep 1 '13 at 12:17
    
Standard, no AD on this server –  IEnumerable Sep 1 '13 at 12:17

If this is a standard DNS zone, the easiest way to back it up and restore it is to simply make a copy of the related zone file; you can find it in C:\Windows\System32\DNS, it's named "your.zone.name.dns".

Yes I found this online just recently, they also noted that they Stopped the server before copying. Is this important? –  IEnumerable Sep 1 '13 at 14:45

It's definitely better, otherwise the file could be locked. –  Massimo Sep 1 '13 at 21:26

That doesn't export the DNS records, it exports a list (txt or csv) of whatever is in the right pane. That's the same functionality as exists in any other tool, such as ADUC.

EDIT:

To clarify, you did not export the DNS records or the zone file. You simply exported a list of the DNS records, or more correctly, you exported a list of the contents of the right pane in the DNS management console. If you want to export the actual zone file then use the dnscmd tool:

It appears you may have forgotten to answer the question? –  Ryan Ries Sep 1 '13 at 14:44

You can't export the zone via GUI, but you can do it via command line:

dnscmd /zoneexport MYDOMAIN.com MYDOMAIN.com.txt

By default the file MYDOMAIN.com.txt will be created in C:\Windows\System32\dns.

Source: dnscmd.
