multihomed dhcp server assigns incorrect ip

I have a multihomed dhcp server and it works fine for
most situations. I have a problem when a client moves
from one subnet to another on the same dhcp server. DHCP
server assigns the ip address from the 1st subnet and now
the client being in the 2nd subnet cannot communicate.

I do not understand why the dhcp server does not delete
the old lease for the client and assign a new one for the
new subnet

Any ideas?
 
Is it a laptop? Did they shut it off before moving it or did they just leave
it run or let it hibernate? It needs to be shut off before moving, then
powered back up.

All you do is configure a Scope (not a Superscope) for each subnet and then
have your LAN Routing Device forward all DHCP Queries to the DHCP Server or
the subnet the DHCP Server is in.

You don't multi-home the machine. It will "serve" multiple subnets perfectly
fine with only one nic while living only on one subnet.
