IIS not working when sharing internet connection

[casperovjp]

My IIS was working when I was not sharing my internet connection. Now it is not(in some way). The scripts will cause a "page can not be displayed" error but basic HTML works just fine. But the rest (coldfusion, ASP, ASP.net, PHP) does not. I'm not particularly sure that the sharing connection is the problem. I installed MS .NET framework and SDK. So I dont know which one is the culprit.

We are using a residential gateway (router) to share connection. I hope somebody out there can help.
