I have one DHCP server running Windows Server 2008 R2. It is configured with one Superscope which contains 5 member scopes. One scope for each one of my subnets.
Here is the problem, if I am on VLAN 12 I get a VLAN 12 IP but if I disconnect my laptop and walk over to a port that is on VLAN 1 and reconnect nothing works. Makes sense because my laptop still has the VLAN 12 IP address. I perform a ipconfig /release followed by a renew but I get the same IP address which is still a VLAN 12 address!
I am guessing this is because my laptop is requesting to have the same IP address. How can I have my laptop not request the same IP? Or better yet, how can I configure DHCP to know that the laptop is on another VLAN and not to give it the same IP?
