The DNS server could not create a zone transfer thread. The system may be out of resources. Close any applications not in use or reboot the computer to free memory. For the specific error code, click the Record Data tab.

The zone transfer request initiated by the master DNS server was refused by the primary server.

Check the specified zone file on the primary DNS server. Verify that the zone name and the secondary master server’s IP addresses have been properly configured in a dotted decimal format. Verify that you can ping each IP address successfully. If you have set the Notify parameters, check the IP addresses and verify that they match the addresses displayed on the General tab of the Zone Properties dialog box.

1. In DNS Manager, right-click the specified zone file, and then click Properties.
2. Verify that the configured IP Master(s) address(es) are valid by pinging each address in the list.
3. If you have set the Notify parameters for your DNS server, and then click the Notify tab.
4. Verify that the IP addresses configured on the General tab are the same as those configured on the Notify tab. If there is a difference between the two lists, only the IP addresses displayed in the Notify list will be used to perform zone transfers if the Only Allow Access From Secondaries Included on Notify List check box is selected.
