Web Services won't run. Why?

[thekingofk2007]

I have a .NET 2005 app which is in a logical 3-tier. Although I can hit the web services locally on my pc, when I copy the app up to the web server, I can not hit them (by putting the URL in the browser). Is there something special I have to do to IIS?Generic error:Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".
