RecursionRetry Registry Key

This registry key determines retry interval for recursive client queries. i.e, If the DNS server does not receive a response for a query with in the time interval, then the DNS server retries the same query to the same server or to other servers.

Key Name: RecursionRetry
Location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters
Type: DWORD
Default: NoKey (3 seconds)
Range: 0x1–0xFFFFFFFF seconds
Functionality: sets interval between repeated query recursive lookups.
By Default, dns server retries after three seconds.
To change the reg value to 10 secs, do the following
reg add "HKLM\SYSTEM\CurrentControlSet\Services\DNS\Parameters" /v RecursionRetry /t reg_dword /d 10

Note:
1. Retries are made continously until RecursionTimeout period reaches.
2. Direct changes to reg key will not be effective until the server reboots.
3. To makes changes without having to restart the server then try with dnscmd.exe
