Cannot connect 2nd Client to server when first client is already loggedIn, happens only incase when server in different network

Hi All, I am building a collaborative application, where two or more clients can logIn to a (remoting) server. My application runs fine, when both the client machines and the server; all three are in same network. But If the client machine are running/accesing the server from a network differnet from where the server is; Only the first client login is sucessfull, and after that second client login fails. Error I get on second client machine trying to login to ther sever: Could not connect to server: System.Runtime.Remoting.RemotingException:Server encountered an internal error. For more information, turn off customErrors in the server's .config file. Server stack trace: Exception rethrown at [0]: at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData&msgData,Int32 type) at MyRemotableClasses.MyRemotableObject.RemoteFunction() at ClientApp.CallRemoteFunction(); _________________________________________________________________________ Code on server which makes remoting channels: ********************************************* string name = NAME +".channel" + cid.ToString(); int port = PORT + cid; IDictionary props = new Hashtable(); props["name"] = name; props["priority"] = "100"; props["port"] = port; BinaryServerFormatterSinkProvider provider = new BinaryServerFormatterSinkProvider(); provider.TypeFilterLevel = TypeFilterLevel.Full; TcpChannel channel = new TcpChannel(props, null, provider); ChannelServices.RegisterChannel(channel, false); WellKnownServiceTypeEntry wkste = new WellKnownServiceTypeEntry(typeof(RemoteClasses.Server), name, WellKnownObjectMode.Singleton); RemotingConfiguration.RegisterWellKnownServiceType(wkste); -------------------------------------------- Client-Side: ******************* BinaryClientFormatterSinkProvider clientProvider = new BinaryClientFormatterSinkProvider(); BinaryServerFormatterSinkProvider serverProvider = new BinaryServerFormatterSinkProvider(); serverProvider.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full; IDictionary props = new Hashtable(); props["port"] = 0; clientChannel = new TcpChannel(props, clientProvider, serverProvider); ChannelServices.RegisterChannel(clientChannel, false); RemotingConfiguration.RegisterWellKnownServiceType(typeof(RemoteClasses.Server), "Server", WellKnownObjectMode.Singleton); server = (RemoteClasses.Server)Activator.GetObject(typeof(RemoteClasses.Server), @"tcp://" + serverip + ":" + port + "/" + servername + ".channel" + channel); ___________________________________________________ Need some troubleshooting tips; as to why the second client fails to login...incase when clients are in a differnt network than that of server (hosting the remotable object). thanks in advance!

Hi Roei , >make sure server port is available. In the channel properties, I have taken the port number to be 0. So that remoting infrastructure can automatically configure the channel, to use a port that is free. So shouldn't that cover it. Also, how would you explain, that the same 2 clients machines accessing the server machine hosting my Remote application are able to login jsut fine when in the same network. But when the clients are in a different network the second client login fails. Cant seem to figure out a definitve solution to this problem thank you for your help!

are you building a since TCPChannel or Channel Per Client? if so make sure that the server port is available. the error you show means that the server connection was successful but he was unable to send back to the client since he was unable to find the Handle to send through the data
