I don't know if there is an easy solution. Here is my advice though. You may not like it, but I am absolutely sincere: get another Web host provider.
Web hosting in Windows servers is crap. I am not one of those annoying Linux fans lurking on every chance to badmouth MS. I still think Windows beats *nix in the desktop environment hands down. I have both in my machine and I spend 95% of the time in Windows. But Windows servers are just not good enough for the job. Not even MS run Windows in their servers. MS's site runs entirely on Unix.
Get yourself another Linux/Unix host provider and forget about these and other possible problems.
