Visual Studio 2010 remote debugging - Unable to connect: Access Denied

Question

I'm trying to remotely debug an exe, but I keep getting an error message. Here's the configuration:

On the dev machine:

• Windows Vista 32-bit
• Visual Studio 2010
• Firewall disabled

On the remote machine:

• Windows 7 64-bit
• msvsmon.exe (shared from the dev machine)
• MyProgram.exe (32-bit, C#, .Net 4.0)
• Firewall disabled

Both machines are on the same domain. I'm logged in with the same account, which has administrator rights on both machines.

And here's what I do:

• Starting msvsmon.exe on the remote computer (using 'run as admin')
• msvsmon output: new server named domain\login@machine created. Waiting for input connections.
• From visual studio: Debug > Attach to process. Filling the Qualifier field with domain\login@machine
• visual studio output: Unable to connect to the Microsoft Visual Studio Remote Debugging Monitor named "machine". Access denied.
• msvsmon output: domain\login connected

What did I miss?

EDIT:

Looks like it's working if the dev machine is 64-bit too (tried on a Win7 x64). So now the question is: how to make it work from my Windows Vista 32?

Answer 1

So the answer is: it's not possible.

To debug a process (either 32 or 64 bits) on a remote 64-bit machine, you have to use a 64-bit machine locally.
