I have two identical servers. Both Win2k3. I have a web service that queues emails and an application that consumes that service. Both are hosted on both machines using identical folder structures, permissions, and IIS settings. One is called "test" and the other "prod".
Ideally, the app on prod will point to the ws on prod. However, when that is the case, I get the following error page:
Server Error in '/Apps/UTMv1' Application.

If the app on prod points to the ws on test, it works. Also, if the app on test points to the ws on prod, it works.
For fun, I tried using the ws on prod in another app. It behaved the same as the original app.
Also, I have other web services running on prod that work properly. This is the only one that seems to be causing problems.
Here's the code I use in the app to new-up the emailer and queue an email:
Emailer e = new Emailer();
e.Credentials = System.Net.CredentialCache.DefaultCredentials;
int intEmailId = e.AddToQueue(fromEmail, toEmail, subject, body, 103, true);
Here's the code for my web service:

using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;

// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.

public class Emailer : System.Web.Services.WebService
{
[WebMethod]
public int AddToQueue(string txtFrom, string txtTo, string txtSubject, string txtBody, int intAppId, bool blnIsBodyHtml)
{
Email e = new Email()
{
From = new MailAddress(txtFrom),
Subject = txtSubject,
Body = txtBody,
IsBodyHtml = blnIsBodyHtml,
AppId = intAppId
};
e.To.Add(txtTo);
e.AddToQueue();
return e.Id;
}
}
}
So, what do you think could be the problem?
