I have IPC set up for my remoting using config files.
I have the channel registered on the server as:
<channel ref="ipc" portName="server" authorizedGroup="Everyone">

I can successfully communicate with the server via a client on this IPC
channel (methods and properties) but when the server raises an event for the
client I get the following error:
"Failed to connect to an IPC Port: Access is denied."

In order to raise the events I am using an intermediate object that is
referenced from both the client and the server. On the server I am looping
through the invocation list for the multi-cast delegate in order to 'raise
the events' and that is where the error occurs. As soon as I attempt to
access a property of the registered client delegate [eg del.Target.ToString()
] I get the 'Access is denied' error.

Note that this works perfectly with tcp....

Any help is appreciated.
