DHCP superscope only assigns addresses from one subscope

    Hello all,

    Since a couple of weeks I'm at loss with a Windows 2003 Server (Standard
    Edition) with DHCP service enabled. I made a superscope containing two
    subscopes. I'll refer to them as "first" and "second" scope.

    When running, the DHCP server gives out leases from the first scope
    only, until no more addresses are available in this subscope. The server
    then begins giving out leases from the second subscope. In the Event
    Viewer, every hour a log entry is created saying: "Scope,,
    is 100 percent full with only 0 IP addresses remaining."

    Is it normal that the DHCP server gives out all leases from one
    subscope? Shouldn't it give out leases from all scopes about equally?
    And why are the system events occuring when in fact there's nothing to
    worry about? I'd really like the server to give out leases from both
    subscopes equally and especially avoiding the system events and the blue
    exclamation mark in DHCP manager.

    Thanks for your replies and hints.

  2. Why do you have two Scopes within a Superscope in the first place?
