One IP cannot access DMZ - can't determine cause

Hi, I've got an issue I've been digging into for some time. Every few weeks, one of my users cannot access our own secure website (via WAN or LAN interface) and receives a connection timeout when trying. Changing the IP address of the PC in question gets everything working again. I can't find anywhere in the firewall log (PIX 515e) that shows anything being blocked, and our ACL enables traffic to flow (almost) freely to our DMZ and has never had a problem before. Could it be a DNS issue? from our internal DNS or external?

Do You access DMZ with your LAN ip address itself?

Accessing the DMZ using Dynamic NAT ?

If you are using Dynamic NAT this kind of issues can persist, then better go for PAT.
