.NET Remoting and Server 2008 (64 Bit)

Question

I have a .NET application that is meant to be run on a local PC and started from a file share on the LAN.

It works fine on 32 bit Windows XP and Vista workstations.

But it fails with a System.InvalidOperationException on 64 bit Windows Server 2008.

It runs fine locally on all three configurations.

What could be the cause?

.NET 2.0 is installed an all machines involved.

Summary:

32 bit XP: runs locally and remotely 32 bit Vista: runs locally and remotely 64 bit 2008: runs locally, fails remotely

"remotely" means running locally but launched from a file share rather than a local drive.

Zone security is set to "full trust" for "Local Intranet" on all machines involved including the 64 bit 2008 machine.

Any ideas?

Answer 1

Are the projects set to run in x86 mode? Use the configuration Manager to check.

Answer 2

My first guess would be Internet Explorer security settings. Try adding your server as a Trusted Site.

Answer 3

This sounds like a security issue, I don't think the instruction set of the CPU makes a difference. I used to have the same problem when running applications from network drives.

I believe this should fix your problem. Caspol
