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
netbios-node-type h-node
default-router 192.168.9.1 255.255.255.0
dns-server 172.26.253.10 192.168.1.60
netbios-name-server 172.26.253.10
domain-name meriden.k12.ct.us
lease 60

On all "user"ports on the 3560 make sure you have implemented the "switchport host" command and then retry your test.

Glen,
Thank you, does that apply even if there are no hosts on this switch but on the upstream switch which is uplinked with a x-over cable?

Apply it on the switch where the win 7 clients are attached but they can't pull an address...

We had a similar problem with Window 7 clients. DHCP is being provided by 2811 routers. Same problem is occurring at several sites. What we found is that the statement default-router 192.168.9.1 255.255.255.0 had to be modified to default-router 192.168.9.1 (with no subnet mask).
Apparently, Windows 7 hosts do not accept the DHCP offer when the subnet mask is included in this statement. We could see the DHCP Discover and DHCP Offer occurring over and over again, but the client would not use the address. Can anyone else confirm this fix?
