I have a 3560 setup to dish out DHCP to clients.
Everyone gets DHCP Correctly with the exception of Windows7 machines.Windows 2000 and XP obtain IP addresses without an issue, but Windows 7 machines do not get an IP address at all. If the Windows 7 machine is moved to a differant subnet where DHCP is offered through our server then the machines get IP's without a problem.
here is my config:
ip dhcp pool franklin-admin
network 192.168.9.0 255.255.255.0
default-router 192.168.9.1 255.255.255.0
dns-server 172.26.253.10 192.168.1.60
