Webmethod not working when webservice published on other server - same data gives "Object Reference Not Set to an Instance of an Object"

Question

Could it be a difference in .Net setup on server? Both have .Net 3.5 SP1

I can see both webmethods when I use url with .asmx name.

Failing on Invoke...

 public int ReferLead(DataTransferObjects.ClientTransferObject request, List<DataTransferObjects.ClientDebtTransferObject> debtrequest) {
            object[] results = this.Invoke("ReferLead", new object[] {
                        request,
                        debtrequest});
            return ((int)(results[0]));
        }

Answer 1

guess nobody has any ideas...
