issues trying to run GUI C# tests with Gallio.echo test runner remotely

Question

I have a set of C# tests that start up and test a GUI. I user the Gallio.echo CLI to run these tests. Running on Windows server 2003 Hudson master is running on Ubuntu the 2003 box is a hudson slave

I can run my tests with gallio.echo locally on my 2003 machine. However, I have a Hudson job that tries to run these tests and it fails, probably because the GUI under test cannot be launched. Error output from Hudson is below:

"""""""""""""""""""""""""

gallio.echo /rt:Xml 'Install Default Path/bin/Debug/Install Default Path.dll'

It appears as though the tests start up but the GUI does not launch due to remote display issues or is hidden and cannot be seen by the tests.

Does anyone run GUI tests on a remote windows machine? Any suggestions on how to solve this issue would be greatly appreciated.

If you run your Windows slave as a service, check the user that it runs under. It it is the Local System account you have to check Allow service to interact with desktop.
