Our Cisco ASA 5505 configured as DHCP server is giving out duplicate IP addresses. Wired connections are getting same IP addresses as Wireless. We have two wireless access points that are using Cisco ASA to assign IP addresses.  

dhcpd dns 10.64.1.51 97.81.22.195
dhcpd auto_config outside
!
dhcpd address 192.168.1.50-192.168.1.200 inside
dhcpd enable inside
!

First I would verify that the c5505 is in fact the only DHCP server on
the network. Do this by running ipconfig /all on a windows system.

Thent I'd look at the bindings table:

c5505-1# sho dhcpd bind

Then I'd try "debug dhcpd event" and check out what's happening at an event level.
