Remoting Question dealing with Microsoft.Sampl es...SSPI,Secur ity

I am absolutely bewildered by now by the Microsoft.Sampl es SSPI and Security
assemblies. I've been trying to set these up in a very straightforward
harness in the way that I'd like to be able to use them. No IIS. Use TCP,
binary. Standard server example with a console host and console client. .NET
1.1, windows XP. (I tried posting to the remoting newsgroup, no answers in
the last couple days, trying here in hopes that more people watch this
group)

I've looked all over, trying to figure out what is going on. I've come
across people reporting similar issues, but no resolution ever seems to be
posted in response. The Host seems to start up fine and be listening. The
constructor for the server object even seems to be called ok. The code for a
particular method/property even seems to execute. I've traced the error into
the ChannelSinkCall Context.Deseria lizeStringToCha nnelSinkCallCon text shown
in the dump. For some reason, at some point, a call to
nextSink.Proces sMessage returns responseHeaders with no
"ChannelSinkCal lContext" header and this in turn passes on to
DeserializeStri ngToChannelSink CallContext as a null which blows up when
Convert.FromBas e64String tries to operate on it.

I've tried everything I can think of in the config files. any suggestions?
If I comment out the provider entities in the below configs everything runs
great. as soon as i try to enable the Security assembly, it blows chunks.
Does it not work with Framework 1.1? XP?

Everytime I try to call a method or property I end up with:

Unhandled Exception: System.Argument NullException: Value cannot be null.
Parameter name: InString

Hi all, I'm creating client/server app in C# (VS. 2003). So, I need the client to call the server with some auth info (user and pass). If the auth is OK, server will do some work and will prepare a zip-file and some other text and numeric data and will notify the client that everything is ready. And the client will fetch the data. So if it was all console/desktop application, I know what to do (in

I have implemented a C# class inherited from System.MarshalByRefObject and using RegisterWellKnownServiceType to allow a web app to communicate with a service on the same machine. I would like to limit remoting of this class to the same machine (i.e. I do NOT want external machines connecting to my class). Is there a way to set security permissions for System.MarshalByRefObject to allow local connections only?

Hi there, I have been messing around with remoting in an attempt to create a "shared application" as mentioned in another thread by that name. I have created a singleton object just like the example in the 101 VB.NET examples. It works great, only 1 instance ever gets created and is shared by each client. I have a few questions though, * Can the singleton contain events? In such a way that when the
