This sounds like a problem with your NAT configuration. I have come across
this situation several times with our customers.
The problem has been that when they static NAT an internal IP, like their
web server, they forget to exclude that address from the dynamic NAT pool.

Subject: DNS and NAT
Is there a solution within IOS to intercept DNS resolution? My issue is
that I have hosts and a WWW server on the same segment. All are being
NATed. The DNS servers sits outside of the Network/NAT and tells the
rest of the enterprise the way to get to the WWW server use this global
IP which has a static translation to the WWW server. The issue is that
when the local host do a DNS lookup they are getting the global IP
rather than the local IP.
I know the PIX can do this with the dns and alias keywords but I am
looking for an IOS solution.
Thanks,
