Site redirects to the wrong site (MII 11.5)

When I type http://xyz04:81 it takes me to http://xyz03:81. We recently switched servers so I understand to a point why it is redirecting to the old site.

I have modified two areas in MII that I thought would fix it;

http://xyz04:81/Lighthammer/Admin/SecurityServers.jsp

http://xyz04:81/LHSecurity/admin/proxy.jsp

It is still redirecting. Could someone please point me to the right location?
