Data type Range Default value
REG_DWORD 0 | 1 1


Determines the order in which the DNS server returns A records (requests for IP addresses) when it has multiple A records for the same name.

Value Meaning
0 The DNS server returns the A records in a fixed, file load order.
1 The DNS server rotates among the A records it returns for a given name. Rotating helps to balance the load placed on each connection to the named server.

Change method

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 Enable Round Robin option. Or, use Dnscmd.exe, a tool included with the Windows 2000 Support Tools. Using either method, your changes are effective immediately; you do not have to restart the DNS server.

Activation method

DNS reads its registry entries only when it starts. If you change the value of this entry by editing the registry, the changes are not effective until you restart the DNS server.

The order in which A records are returned depends on the value of LocalNetPriority and the value of RoundRobin, as follows:
