Hi all,
In order to avoid conflict with other ips in the vlan you could also use:
ip dhcp ping packets 1
This would get the server to ping the ip address before assigning it to make sure nobody else is using it.

Eric, this is correct. However, by default, the DHCP server pings a pool address twice before assigning it to try and make sure it isn't in use. If it doesn't get a response it assumes its available and assigns the address so I really don't think adding this command is necessary unless you wanted to reduce the number of pings from 2 (the default) to 1. I found this information on the following link in case anyone wants to verify: http://www.ccda.biz/en/US/docs/ios/12_2/ip/configuration/guide/1cfdhcp.html#wp1001176

In Solution guide for this secrtion interfaces used on R5 should be "FastEthernet 0/0".
