For some reason, some of my desktops/laptops are not auto logging into ZENworks.
When you right-click on the blue ZENworks icon in the system tray, it gives you the option to "login" after logging in under an AD account on Windows XP Pro SP3.
I have tried unregistering and re-registering the machine from ZENworks but still no luck.

This problem occurs consistently on certain individual machines so I don't think the issue is user related.

Any ideas?
