ASA5510 DHCP issuing duplicate leases

Lately our office has been recieving duplicate IP address errors when logging into workstations in the morning.

I've tried clearing the DHCP bindings with no luck. What is the next step to troubleshoot why the DHCP has stale lease info and/or why it is handing out bad IPs?

ASA5510 DHCP config as follows:

dhcpd dns 10.0.0.25 10.0.0.55

dhcpd wins 10.0.0.25 10.0.0.55

!

dhcpd address 10.0.0.100-10.0.0.254 inside

dhcpd lease 172800 interface inside

dhcpd enable inside

!

dhcpd address 192.168.1.2-192.168.1.254 management

dhcpd enable management

!

Thank you in advance.

Re: ASA5510 DHCP issuing duplicate leases

Are your inside systems pingable from the firewall?

Also, why is your lease timeout set to such a high value (default is 1 hour)?
