    I have a Windows 2003 dhcp server that has a super scope with two scopes in it they are 192.168.199.x and 192.168.200.x. The 200 subnet is full so the server has started giving out IPS in the 199 subnet.  Most of my machines will take a IP in the 199 subnet but I have some machines that I'll not pickup an IP in that range. I can assign them a 199 address statically and they work fine but they won't pickup a address in the 199 range dynamically.  However if a 200 subnet IP becomes available they will pick up one of those.  Does anyone have an idea on what is causing this?

    Hi,

    Thank you for the post.

    Most of my machines will take a IP in the 199 subnet but I have some machines that I'll not pickup an IP in that range.
    Please verify these machine connected switch/router could transfer DHCP broadcast to your DHCP server (relay agent to both DHCP server 199.x and 200.x ip address). You could use netmon to capture the DHCP packet on your client.
