I had created a setup for my web service by using MS Visual .Net. Then I do the setup in one testing machine. The IIS virtual dir setting was correctly created after the cross checking and I had successful to browse the web service in that testing machine (local access). The PROBLEM is I can't find the web service when I trying to add the web references in my development machine even I had cross check the address path was correct. Is that any setting that I missed up during the deployment? Thanks!
