|Data type||Range||Default value|
|REG_DWORD||0x1 - 0xFFFFFFFF seconds||0x3|
Determines how often DNS repeats recursive client queries when it does not receive a response from a remote server. If the DNS server does not receive a response before the time specified by this value expires, the DNS server repeats the query to the same server or to other DNS servers.
The default value is appropriate for most servers. However, if this value is less than the time it takes for a remote server to respond over a slow link, you should increase this value so that it is slightly longer than the observed response time.
To change the value of this entry, use Dnscmd.exe, a tool included with the Windows 2000 Support Tools. The change is effective immediately; you do not have to restart the DNS server.
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.
