Ok, now we are getting somewhere.

If I understand this correctly, you have implemented a webmethod within your asp.net website in an asmx file (something that we are also doing in one of our products as well). In order for this to work properly in IIS (works fine in development environment), you will need to configure your IIS to allow .asmx pages (add a handler mapping). You can do this directly in the IIS config, or in your web.config.

Here is another question for reference:

ASMX service works on development server, returns 404 when deployed to IIS 7.5

Disregard bounty thing. Different question :)
