dhcp rety time reg key RRS feed

  • Question

  • HI,
    I would like to know if the registry keys,
    are used for anything other than the DHCP retry timer?
    This question specifically applies to XP operating system.  However, we will be moving to Windows 7 next year and will be interested to know the answer to my question under Windows 7 operating system too.

    We currently have a condition that the DHCP server running on the router does not start until about 60 seconds after the Ethernet link comes up.
    As the result the 4 DHCP Discovery messages are not answered by the DHCP server.
    And so the Data terminal (running XP operating system) waits about 360 seconds before re-sending DHCP Discovery messages (i.e. ask for IP address) to the router.

    We have found that by adding the above mentioned 2 keys, and setting them to value of 1, the retry of DHCP Discovery messages occurs in about 61 seconds.

    Could you please let us know if adding the above mentioned 2 registry keys have any side effects other than decreasing the retry time for DHCP retries?
    And is there any problem with setting this value to 1 (default is 300) sec?
    Finally, can the same registry be used for Windows 7 or should we use a different mechanism?
