WindowsError: [Error 5] Access is denied

[Jimmy Chan]

Hello,

I have Hudson 1.303 and a slave node connected via JNLP agent. The
slave node is running Windows Vista. I have windmill 1.1.x and python
2.5.4.

I set up a Hudson job to run a simple command:

windmill firefox http://www.google.com

When run the job, Hudson reports this error:

Traceback (most recent call last):
File "c:\python25\scripts\windmill-script.py", line 8, in <module>
load_entry_point('windmill==1.1.1', 'console_scripts', 'windmill')

WindowsError: [Error 5] Access is denied.

However, when run the command manually on the slave machine, it runs
successfully.

The same Hudson job runs fine when using a Windows XP slave node.

Any idea how to debug this issue?

Has anyone successfully run windmill tests on Windows Vista via
Hudson?

Thanks in advance.
Jimmy
