.NET Remoting on Inspiron 8600c

​I've got an Inspiron 8600c running Windows XP Professional with Service Pack 2. I'm trying to do some software development using Visual Studio .NET 2003 and the .NET Framework v1.1, specifically related to .NET Remoting. However, my application hangs on any method call to the remote object. The Remoting channel appears to be created successfully, but there is no response when any calls are made to the remote object.​

​I have tried most of the Microsoft samples and none of them work when the client and server are on my Inspiron laptop. When the server is on a different machine it works fine, but not the other way round, i.e my Inspiron is fine acting as a Remoting Client, but not as a Remoting Server.​

​The SP2 firewall has been turned off and it has been proven and tested that other means of communicating with the laptop (such as file transfer) work correctly. I have tried uninstalling and reinstalling the .NET Framework, but the problem still persists.​

​Has anyone else come across this problem? Does anyone know how to resolve it?​
