I'm trying to enable dhcp server on a cisco router, but it doesn't works.
The client dhcp I use for testing (a WIndows XP) doesn't get the address.
But the cisco router says that it was binded to the test pc. What can be
wrong?

For testing I connected a spare router to the 10.10.10.0/24 segment. I
configured the interface ethernet 0 with address 10.10.10.34/24. The other
interface (serial 0) is configured but not connected to any device. I'm
trying to use the router as a DHCP server for testing the configuration
before trying on the production router.

The dhcp specific configuration is the following:

ip dhcp database ************ // I tryed also "no ip dhcp conflict
logging" command

ip dhcp excluded-address 10.10.10.1 10.10.10.60
ip dhcp excluded-address 10.10.10.64 10.10.10.254
!
ip dhcp pool net10
network 10.10.10.0 255.255.255.0
domain-name matusa.net
dns-server 10.10.10.1
netbios-name-server 10.10.10.1
netbios-node-type h-node
default-router 10.10.10.254
lease 2

When configured with DHCP the XP, and after restarting it, the "show ip dhcp
binding" command states:

IP address Hardware address Lease expiration Type
10.10.10.62 0100.c09f.411e.af Sep 27 2004 07:00 PM Automatic

The hardware address is the same of the XP PC, but it looks like the PC
doesn't acknowledges the leased address.
What can be wrong?

Thanks in advance. The full router configuration is the following:

If my email address starts with two 'f'
drop the first 'f' when mailing me.

put a packet capture program like Etherreal on PC to see if it
actually receives a DHCP server response

Dunno. Get a "debug ip dhcp server packet" and release renew on the
Windoze box. Might tell you something?

Wise advice. The problem was on a second unknown dhcp server on the segment.
It was a wireless hub somebody installed and leave the dhcp server option ON
without properly configuring it. Useful stuff that Ethereal. Thank you guys
