Richard et al,
When the call fails, I get an exception saying that an internal error
occurred:
System.Runtime.Remoting.RemotingException: Server encountered an internal
error. For more information, turn on customErrors in the server's .config
file.

I tried to turn on custom errors in the server component, but it make any
difference - I didn't get any more information.
Does this help at all?
Thanks!

When you say the calls fail, in what way do they fail? If you get an
exception can you show the exception trace. A bit more diagnostic
information will aid people in resolving your problem so can you add the
extra information and repost your message to the list.

Subject: Passing a MarshalByRefObject as an input parameter causes error -
URGENT
Hi all,
I'm working on a client/server application using .NET remoting. I
have several objects in a class library that inherit from
MarshalByRefObject. One of these classes is registered as a
WellKnownType by the server and retrieved by the client through a call
to Activator.GetObject(). All the other classes (around 20, I think)
are retrieved as output parameters from subsequent function calls to
this well-known class.
Most of my function calls work just fine. However, I'm having
trouble when I make "complex" function calls. There are two types of
calls that seem to fail; the first type takes one of my
MarshalByRefObjects as an input parameter, the other is a function
that takes a basic type (int, string, etc.) as an input parameter, and
I pass the result of an accessor function of a MarshalByRefObject as
the input parameter. Both of these call types fail. The latter I can
get around by creating temporary variables. However, I don't know of
a way to solve the former problem (the MarshalByRefObject as an input
parameter). I tried registering all my MarshalByRefObject classes as
well-known types, but this didn't resolve my issue. I've also tried
implementing the ISerializable interface in all the classes, but still
had no luck.
One other strange complication to this issue - if I run both the
client and server portions on the same machine, the function calls
execute correctly. They only fail when the server and client are
running on two different machines. I've tried both a Windows
Application and a Web application for the client piece, but neither
option makes a difference.
I need to resolve this problem quickly. Any help/suggestions are
welcome and greatly appreciated.
Thanks in advance.
