I have a wcf service where i have to implement the call backs and also i need to host the wcf service on the IIS 6.0, since IIS6.0 doesnot support the net.tcp binding, i decided to go for the custom binding. The reasons for going for custom binding is that the service is accessed by different clients in different timezones. Using custom binding i can set the allowed clock skew time to other values other than the default one.

I have problem making the custom binding work for me. here is the server config file

<bindings>
  <customBinding>        
    <binding name="pscNetBinding" openTimeout="00:10:00">          
      <reliableSession acknowledgementInterval="00:00:00.2000000"
  flowControlEnabled="true" inactivityTimeout="23:59:59"
  maxPendingChannels="128" maxRetryCount="8" maxTransferWindowSize="128"
  ordered="true" />
      <compositeDuplex />
      <oneWay maxAcceptedChannels="128" packetRoutable="false">
        <channelPoolSettings idleTimeout="00:10:00"
  leaseTimeout="00:10:00" maxOutboundChannelsPerEndpoint="10" />
      </oneWay>
      <textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"
  messageVersion="Default" writeEncoding="utf-8">
        <readerQuotas maxDepth="2147483647"

  maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
      </textMessageEncoding>
      <httpTransport manualAddressing="false"
  maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"

  keepAliveEnabled="true" maxBufferSize="2147483647"
  proxyAuthenticationScheme="Anonymous" realm="" transferMode="Buffered"
  unsafeConnectionNtlmAuthentication="false" useDefaultWebProxy="true"/>
    </binding>
  </customBinding>
</bindings>

<services>
  <service name="SchneiderElectric.PSCNet.Server.Services.PSCNetWCFService" behaviorConfiguration="Behaviors1">
    <host>
      <baseAddresses>
        <add baseAddress ="http://10.155.18.18:2000/PSCNet"/>
      </baseAddresses>
    </host>
    <endpoint address="" binding="customBinding"    bindingConfiguration="pscNetBinding"
                                contract="SchneiderElectric.PSCNet.Server.Contracts.IPSCNetWCFService"/>
  </service>
</services>    
<behaviors>
  <serviceBehaviors>
    <behavior name="Behaviors1">
      <serviceMetadata httpGetEnabled = "true"/>

      <dataContractSerializer maxItemsInObjectGraph="2147483647" />-->
    </behavior>
  </serviceBehaviors>
</behaviors>

and here the client config file

  <bindings>
    <customBinding>
      <binding name="pscNetBinding" openTimeout="00:10:00">            
        <reliableSession acknowledgementInterval="00:00:00.2000000"
    flowControlEnabled="true" inactivityTimeout="23:59:59"
    maxPendingChannels="128" maxRetryCount="8" maxTransferWindowSize="128"
    ordered="true" />
        <compositeDuplex />
        <oneWay maxAcceptedChannels="128" packetRoutable="false">
          <channelPoolSettings idleTimeout="00:10:00"
    leaseTimeout="00:10:00" maxOutboundChannelsPerEndpoint="10" />
        </oneWay>
        <textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"
    messageVersion="Default" writeEncoding="utf-8" >

        </textMessageEncoding >

    unsafeConnectionNtlmAuthentication="false" useDefaultWebProxy="true" />                    
      </binding>
    </customBinding>
  </bindings>
  <client>
    <endpoint address="http://10.155.18.18:2000/PSCNet" binding="customBinding"
        bindingConfiguration="pscNetBinding" contract="PSCNetWCFService.IPSCNetWCFService"
        name="pscNetBinding" />
  </client>

if i use the server and client on the same machine everything works fine. But as soon as i run the server and client on different machine i get the following error

"Could not connect to http://10.155.18.198:9000/e60ba5b3-f979-4922-b9f8-c820caaa04c2. TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.155.18.198:9000."

Can anyone in the community help me in this regard.
