Remoting in Citrix Environment

Hi,

I have a winforms app that is going to be deployed across a Citrix server farm. The application GUI uses remoting to contact a dedicated server that provides business objects & data access etc.

I noticed today that if two users are connected to the same Citrix server & both attempt to launch the application, the second user will fail with 'Only one usage of each socket address (protocol/network address/port) is normally permitted' exception - how should this issue be handled? I'm using the RemotingConfiguration.Configure(configFile) method to load the remoting configuration which holds the port number. Should I omit this information from the config, then try to grab an unused port??

Any advice appreciated!

Thanks
Dylan
