I've done a little research on this, and will continue to do some more... but one solution for people that are having this problem is disable the firewall and see if that corrects the problem. Shouldn't depend on the skin, beause if you look right in that screenshot, it's a DNS error, which SHOULD have nothing to do with the skins.
Terry, if you could double check how the DNS is set up on the server and double check it's all correct on that side, that would be great.

There's a google search if anyone has time to browse some of the results to try and find out why this is happening.
