>On my development PC, where I installed VS.NET, pulling out http://localhost/.../MyWebService.asmx will show me the methods and the WSDL will work as well. However, after I copied the three ASMX files on the server for a test phase, when pulling it out from the browser, it seems the file is not registered as the browser tries to download the file. I thought that the .NET Framework was enough on the server as far as the requirement goes. What else should I do on the server so it'll be ready to handle all that?

Ok, this is resolved. I had to update the .NET Framework to 1.1 and it does the trick.
