            <add name="HttpSOAP12" />
        </protocols>
    </webServices>
</configuration>

Answer 2

<Configuration>
 <system.web>
   <webServices>
     <protocols>
        <remove name="HttpSOAP"/>
        <add name="HttpSOAP12"/>
     </protocols>
  </webServices>
</system.web>

websServices needs to be enclosed within the system.web section. If not the soltuion throws error " The configuration section 'webServices' cannot be read because it is missing a section declaration "
