Hi Experts,
Our existing WCF service giving an error.
The error is as follows:


-		ex	{"The maximum message size quota for incoming messages (6354600) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element."}	System.Exception {System.ServiceModel.CommunicationException}

After changing the following value 999999999 to everywhere in the following binding



<bindings>
      <customBinding>
        <binding name="SilverlightBinaryBinding">
          <binaryMessageEncoding>
            <readerQuotas maxStringContentLength="999999999" maxArrayLength="999999999" maxDepth="999999999"/>
          </binaryMessageEncoding>
          <httpTransport maxReceivedMessageSize="999999999"/>
        </binding>
      </customBinding>
      <basicHttpBinding>
        <binding name="CustomBasicHttpBinding" maxReceivedMessageSize="6355600"/>
            <binding name="CumulusWS8PortBinding" closeTimeout="00:01:00"
            openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
            allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
            maxBufferSize="999999999" maxBufferPoolSize="999999999" maxReceivedMessageSize="999999999"
            messageEncoding="Mtom" textEncoding="utf-8" transferMode="Buffered"
            useDefaultWebProxy="true">
            <readerQuotas maxDepth="999999999" maxStringContentLength="999999999" maxArrayLength="999999999"
            maxBytesPerRead="999999999" maxNameTableCharCount="999999999" />

then it throws the following error


{System.Net.WebException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned an error: NotFound.
   at System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncResult asyncResult)
