| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0 | 1 | 1 |
Enables the server running DNS to interoperate with non-Microsoft DNS servers that use an older, slower version of the DNS BIND service.
| Value | Meaning |
| 0 | The Microsoft DNS server places as many resource records as possible in each message to achieve maximum compression and speed of transfer. Microsoft DNS servers and non-Microsoft DNS servers that use BIND version 4.9.4 or higher can receive transfers in this format. |
| 1 | The Microsoft DNS server sends zone transfers to non-Microsoft DNS secondaries with one resource record per message. Non-Microsoft DNS servers using BIND versions prior to 4.9.4 cannot receive the transfer unless it is in this single resource record per message format. |
To change the value of this entry, use the DNS console. Right-click the server name, click Properties, click the Advanced tab. This entry corresponds to the Bind Secondaries option in the Advanced server options list.
DNS reads its registry entries only when it starts. You can change entries while the DNS server is running by using the DNS console. If you change entries by editing the registry, the changes are not effective until you restart the DNS server.
Note
Transfers between Microsoft DNS servers always use the faster, high-compression method, regardless of the value of BindSecondaries.
The default value is appropriate for most DNS servers. Set this value to 0 only when you have NEW BIND servers (or non-BIND, non-Windows servers) which are secondaries to Microsoft DNS server and transfer performance is a high priority.
