I went to the site to try to get some answers from there, but I couldn't get any of the links to work. It looks from the front page, that ithium.net runs on Linux servers (as canislupusyo says - the penguin is a hint).
My suggestion is: find out exactly what type of ASP support his servers have (eg: Chili!Soft ASP), and research that version. There might be objects or syntax that are different, and causing the problem (I'm not a Chili!Soft ASP expert, so I can't help you much more).
Most linux based setups including cpanel only offer a limited support for ASP as an apache module (very limited) there are software applications out there that will give you close to full asp support on linux systems (expensive) but windows and IIS have a number of reasons why its better then linux and ASP is one of them. and vice versa linux has a number of reason why its better then windows IIS servers.
but again if your going ASP go windows IIS server.
