You've actually provided very little information which makes it difficult to troubleshoot. You've not listed any urls so that other people might be able to run some tests. So, at this point, I don't think anyone on the board will really be able to do much more than point you in the direction to fix the problem yourself.

First, make sure you don't have any malware/spyware on your machine. If you have a router, connect without using the router. Make sure your settings match what your ISP says they should be. You mention it does it on IE and Firefox, which means it might not be an issue with IE specifically, but, there is malware that will infect the hosts file or could have changed your TCP/IP properties. It could be further upstream if you use a router that has a content filter.

Then, approach the sponsor, tell them the difficulties you're having and have them work through some troubleshooting with you. At some point, they're going to find out if it is a dns issue or a connectivity issue based on whether some tests work and some don't. For example, if you cannot get the dns to resolve, but, can hit the IP address that the hosted galleries are hosted on, then the dns issue needs to be resolved. Perhaps you need to try opendns, perhaps you have malware, perhaps your ISP has blocked that IP for some reason, perhaps your router/firewall is blocking the domain name because of some filter or doing some content filtering.

Once you've gotten the issue hammered down to a few alternatives, if its not a sponsor issue, then, you have the Internet Provider's technical support to head to. You give them the information, they run some diagnostics, checks, etc to find out whether the issue is on their side or your side.

If its determined to be on your side, then, you run your spyware/malware scans, check the connection settings with your machine to make sure they match what your ISP claims they should be.

At some point in that process it should fix it.

Good luck.
