WDNS-IA-000004 - The Windows DNS primary server must only send zone transfers to a specific list of secondary name servers.

Information

Primary name servers also make outbound connection to secondary name servers to provide zone transfers and accept inbound connection requests from clients wishing to provide a dynamic update. Primary name servers should explicitly limit zone transfers to only be made to designated secondary name servers. Because zone transfers involve the transfer of entire zones and use TCP connections, they place substantial demands on network resources relative to normal DNS queries. Errant or malicious frequent zone transfer requests on the name servers of the enterprise can overload the master zone server and result in DoS to legitimate users.

AD-integrated DNS servers replicate zone information via AD replication. Non-AD-integrated DNS servers replicate zone information via zone transfers.

Solution

Log on to the DNS server using the Domain Admin or Enterprise Admin account or Local Administrator account.

Press Windows Key + R, execute dnsmgmt.msc.

On the opened DNS Manager snap-in from the left pane, expand the server name and then expand Forward Lookup Zones.

From the expanded list, click to select the zone.

From the displayed context menu, click the 'Properties' option.

On the opened zone's properties box, go to the 'Zone Transfers' tab.

On the displayed interface, select the 'Allow zone transfers' check box.

Select the 'Only to servers listed on the Name Servers tab' radio button OR select the 'Only to the following servers' radio button.

Click on 'Apply'.

Click on 'OK'.
