Description:
A zone transfer request for the secondary zone sofia.san.ru.local was refused by the master DNS server at 192.168.111.31. Check the zone at the master server 192.168.111.31 to verify that zone transfer is enabled to this server.  To do so, use the DNS console, and select master server 192.168.111.31 as the applicable server, then in secondary zone sofia.san.ru.local Properties, view the settings on the Zone Transfers tab.  Based on the settings you choose, make any configuration adjustments there (or possibly in the Name Servers tab) so that a zone transfer can be made to this server.
