Clients of published Web services may not receive server script time-out errors

If Web clients that use .NET Framework 2.0 are calling a Web service generated with the BizTalk Server 2006 Web Services Publishing Wizard, it is possible that the client cannot receive server script time-out errors because the client request time-out occurs first by default. To resolve this problem you can do one of the following:

· Increase the client request time-out to a value greater than the server script time-out by increasing the value for the HttpWebRequest.Timeout property on the client.

· Reduce the server script time-out to a value less than the client request time-out by reducing the value for the HttpServerUtility.ScriptTimeout property on the server.
