BindSecondaries

HKLM\SYSTEM\CurrentControlSet\Services\DNS\Parameters

Data type

Range

Default value

REG_DWORD

0 | 1

1

Description

Enables the Domain Name System (DNS) server to communicate with non-Microsoft DNS servers that use an earlier, 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 in each message. Non-Microsoft DNS servers using BIND versions prior to 4.9.4 can receive the transfer only in this format.

Change method

To change the value of this entry, use the DNS console. Right-click the server name, click Properties, and then click the Advanced tab. This entry corresponds to the Bind Secondaries option in the Advanced server options list.

Activation method

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 Image Note

Transfers between Microsoft DNS servers always use the faster, high-compression method, regardless of the value of this entry.

The default value of this entry is appropriate for most DNS servers. Change the value of this entry to 0 only if you have NEW BIND servers (or non-BIND, non-Windows servers) that are secondaries to a Microsoft DNS server and if transfer performance is a high priority.

Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
