How do you grow the subnet mask for 2003 DHCP?

Discussion in 'Windows Networking' started by Mark Rechenberg, Nov 30, 2003.

  1. I have the situation of needing to grow the subnet mask on my DHCP from
    255.255.254.0 to 255.255.252.0 but it seems that this can't be done via the
    DHCP mmc plugin. I have a lot of reservations that I really don't want to
    re-type.

    Any assistance is greatly appreciated.

    Regards,

    Mark.

  2. Use

    Netsh DHCP Server \\%IPADDRESS% dump > C:\DHCP.dmp

    Make your modifications to the DHCP.dmp file ( This is the current config of
    your DHCP server )

    Then playback the file by using

    Netsh Exec C:\DHCP.dmp

    This will allow you to expand the range and keep your reservations with as
    little effort as possible
