assistance in transferring to different host

Need quick help, easy job for someone who understands what is going on. Webaddress is [login to view URL] We had a rather large website built, but the host was unable to handle the load, so we attempted to transfer the files to another host. ModVPS from [login to view URL] we were told all issues would be resolved. The DNS is through GoDaddy we keep getting the following emails: The hostname ([login to view URL]) resolves to . It should resolve to 207.210.99.138. Please be sure to correct /etc/hosts as well as the 'A' entry in zone file for the domain. Some are all of these problems can be caused by /etc/[login to view URL] being setup incorrectly. Please check this file if you believe everything else is correct. You may be able to automaticly correct this problem by using the ' Add an A entry for your hostname ' under ' Dns Functions ' in your Web Host Manager. ******************************************************* know this is an easy fix for someone who understands, my current webdesigner doesn't know what to do.
