We have recently transitioned to a DHCP-based IP addressing scheme on a LAN where all the users are connected to a Catalyst 4006 (version 6.3(1)). The switch has port security employed on nearly all the ports. Several PCs are experiencing lockout conditions when they release and renew their IP configurations. When moved to ports that don't have port security, they have no problem. Though port security is done by MAC address and you would not expect problems with DHCP IP configuration, the evidence is there that they are conflicting with each other. Has anyone seen this problem? We are considering removing port security on the switch but we really don't want to.
