[users@httpd] Apache not catching DNS

[David Rickard <David.Rickard@xxxxxxxxxxxxx>]

System: Solaris SunOS 5.9
Apache: 2.0.52
Tomcat: 4.1.31
Mod JK: 1.2.6

We have a Java webapp which we are moving to a new server.  
For initial testing on the new machine, we configured Apache and Tomcat
to use the machine name, i.e. the ServerName directive in httpd.conf
is:

        

ServerName
server.company.com:80
the Host value in server.xml is:

        

<Host
name="server.company.com" debug="0"
appBase="webapps"
and the host value in workers.properties is:

        

worker.ajp13.host=192.168.12.34
[this is the base IP of the machine]

With this configuration, the webapp works perfectly: point a browser to
http://server.company.com/webapp/
and the site behaves as it should.

This morning, we disconnected the old machine from the network, added the webapp DNS IP to /etc/hosts on the new machine, updated httpd.conf, server.xml, and workers.properties to use the DNS, and restarted the server; and now the site cannot be found; browsing to http://public.site.com/webapp/ produces a standard "Cannot find server" page; browsing to http://server.company.com/webapp/ still produces the (static) index page, but calls to dynamic pages (servlets/JSP) fail (presumably because Tomcat expects requests from public.site.com).  I suspect that this may be an IP/network issue (pinging public.site.com on the new machine times out)--but the network guys insist everything is configured correctly (ifconfig produces the expected results on the server); but assuming that it is an Apache issue, what is likely to be wrong?
