Help required on remoting

Hi,

I'm using remoting in .Net

I'm getting the following exception message during deserialization...
"Because of security restrictions, the type XXX cannot be accessed..."


Here is the Stack Trace:

Server stack trace: at System.Runtime.Serialization.FormatterServices.GetSafeUninitializedObject(Type type) at System.Runtime.Serialization.Formatters.Binary.ObjectReader.ParseObject(ParseRecord pr) at System.Runtime.Serialization.Formatters.Binary.ObjectReader.Parse(ParseRecord pr) at System.Runtime.Serialization.Formatters.Binary.__BinaryParser.ReadObjectWithMapTyped(BinaryObjectWithMapTyped record) at System.Runtime.Serialization.Formatters.Binary.__BinaryParser.ReadObjectWithMapTyped(BinaryHeaderEnum binaryHeaderEnum) at System.Runtime.Serialization.Formatters.Binary.__BinaryParser.Run() at System.Runtime.Serialization.Formatters.Binary.ObjectReader.Deserialize(HeaderHandler handler, __BinaryParser serParser, Boolean fCheck, IMethodCallMessage methodCallMessage) at System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.Deserialize(Stream serializationStream, HeaderHandler handler, Boolean fCheck, IMethodCallMessage methodCallMessage) at System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.UnsafeDeserialize(Stream serializationStream, HeaderHandler handler) at System.Runtime.Remoting.Channels.CoreChannel.DeserializeBinaryRequestMessage(String objectUri, Stream inputStream, Boolean bStrictBinding, TypeFilterLevel securityLevel) at System.Runtime.Remoting.Channels.BinaryServerFormatterSink.ProcessMessage(IServerChannelSinkStack sinkStack, IMessage requestMsg, ITransportHeaders requestHeaders, Stream requestStream, IMessage& responseMsg, ITransportHeaders& responseHeaders, Stream& responseStream) 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 ABCD.RemoteFacade.IRemoteDownload.GetService(DownloadRequestParameters downloadRequest) at ABCD.btnRemoting_Click(Object sender, EventArgs e) in d:\ownership\src\web.ui\equitylookuptview.ascx.cs:line 256

I tried setting typeFilterLevel="Full" in the code, but still it I get the same exception.

Where am I going wrong... Please help.

Thanks in advance..
