WCF / ASMX :: Getting 403 Then 404 Error On Web Service That Was Working On Prior Server?

I have a web service that was running on Server 2003, IIS6. The service required an SSL connection. The service expects 4 parameters; a User ID, Password, Record ID and the "type" of data requested (one of 5 options). The service validates the user then simply performs a select of the record ID from a table determined by the type specified. This service was up and running for a couple of years. I installed a couple of new servers a couple of months ago. The users that makes use of this service just tried it and couldn't get a response. I checked the server and I hadn't copied the service over. The service is located in a virtual directory under the primary web site.

For example, the site is: [URL] Service virtual directory is "GetITSData" The call to the service has been: [URL] param1, param2, param3, param4 and the service would return the appropriate data. I "assumed" that when I copied the actual contents of the directory over, that the service would then begin functioning again (since it was empty). All IIS snap-in manager items for the virtual directory match the previous settings on the old server (I still have that server available in my office). The main site requires SSL and uses forms authentication. When I create a dummy site in VS2008 and try to add a service reference, I get the following: There was an error downloading [URL]. The request failed with HTTP status 403: Forbidden. Metadata contains a reference that cannot be resolved: [URL]. The remote server returned an unexpected response: (405) Method Not Allowed. The remote server returned an error: (405) Method Not Allowed. If the service is defined in the current solution, try building the solution and adding the service reference again.
