We are moving a particular server offsite to a remote data center and they are now hosting the server and application. We have established an IPSEC Site-to-Site VPN tunnel using two ASA5510s. We were given an IP address of the server that will now be hosting our application. If I go to http://147.XXX.XXX.84/app then the login form pops up, I enter my credentials, and everything works with no problems.
I want to try to make things easier on our users so they don't have to remember the IP address so I tried creating an A Record() DNS entry in our Windows 2003 DNS server. If I create the A record and I try to access http://Arecord/app, the login form pops, I enter my credentials, then I get an error. I believe that error is happening because the address is now http://Arecord.mycompany.org/app/JumbleGarbageTheAppUsesForNavigation.
So my question is, how do i create a DNS record that will allow me to replace the IP address and still allow the web app to function properly? I'm not sure how to get it to stay http://Arecord and not change to the FQDN
