DHCP client failed to get an ip address when connected to another

[Guest]

hello. I have some laptops (dhcp clients) on network 192.168.1.0 working fine
by obtaining ip from a dhcp server.

The problem now comes if they are taken to another network (172.16.1.0)
(since their ip address 192.168.1.x have not expired) , they fail to obtain
ip address automatically from that network dhcp server, rather they maintain
their 192.168.... ip unless I issued ipcconfig /release and then ipconfig
/renew, then they get 172.16...

I want my staff to be able to plug in their laptop and start working
irrespective of the network connected to without making any config changes
since the dhcp servers are working well. Please help!

Shut the laptops down before moving them,...don't just hybernate them or put
them in standby. They only contact a DHCP Server on bootup and when the
lease runs out,..otherwise they will keep the address they have and will not
contact a DHCP even if they get moved to a new wire.
