Erratic System.NullReferenceException

Hi I have a project I have client in PC A and server in PC B (SAO and
Singleton).

I get an instance of object in B and I pass to B a reference to another
object hosted in A in the same client process. Then from B I call a method
to object A sent.

This thing works fine allways in my lan, but some friends test this system
in 2 PCs direct connected by a cross RJ45 cable, so no DNS. and some times
work and some times does not. They have tested many PCs (fresh installed)
and the only combination that work sometimes is PC A on Windows Xp and PC B
on Win 2K.

Does the direct cable and no DNS server or windows domain has something to
do with this errors ?

Thanks

See if setting machineName to the IP of the machine will work.

Incredibly the only test that ocasionally worked in those direct linked PCs
was using their name instead of the IP address :-(

thanks for asking

Any exceptions? When?

Microsoft .NET Remoting is SOA Applied. By using .NET Remoting you will
be developing against a Service Oriented Architecture, by following
basic SOA guidelines you will have a Service Oriented Architecture
end-to-end.

I have read a few SOA books and I have been using .NET Remoting since
2002, if you have specific questions on how to implement specific
patterns ask here and I will try to reply as I have time.
