PIX DCHPD handing out multiple IPs to single MAC

Hello,

We are having problems with DHCPD handing out addresses to WYSE 1200 Citrix terminals. A 501 and 506 firewall will occasionally hand out multiple IPs to a single mac address. When I do a 'show dhcpd binding' you can see the same mac address attached to multiple IP addresses. We are using 6.3.4 IOS. Any ideas?

For clarity:

This is an issue you have noticed on distinct lans, one of which has a 501 and the other a 506?

Or is this an issue you have noticed on a single lan that has both a 501 and 506 connected with dhcpd active on both of them?

These are distinct lans in different towns. Sorry for any confusion.

Are the Wyse winterms the only DHCP clients or are there other device types at these two locations.

Have you ever capture the DHCP packet exchange between one of these Wyse winterms and a PIX configured as a DHCP server? If not I would do that to ensure there is nohing anything usual about the exchange.
