To Configure the TTL Value
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that you can solve
problems that result from using Registry Editor incorrectly. Use Registry Editor at your own
risk.
A new feature has been introduced with this fix. You can use this feature to configure the TTL value in the registry.
- Click Start, click Run, type regedit.exe, and then click OK.
- Locate and then click the following key:
HKLM\SYSTEM\CurrentControlSet\Services\DhcpServer\Parameters
- Double-click the DynamicDNSTimeToLive value.
NOTE: If this value does not exist, create it as a DWORD value. - Set the DynamicDNSTimeToLive value to the TTL value that you want to use. Set the value in seconds (for example, for a value of 20 minutes, set the value to 1200).
- Click OK.
- Quit Registry Editor. The new value takes effect the next time that the DHCP service is started.
