Create process in Citirx environment

[jfjoyner]

I'm working on a SSO (Single Sign-On) project that we are trying to launch in a Citrix environment. Our environment is Citrix XP running on Win2000 Server and ICA clients running on Win2000 Professional. The SSO is in the form of a toolbar, and it is the published app launched from the user's client machine. The published app launches fine and the toolbar appears within the Citrix session. The problem is with the toolbar actually launching the apps. We are using the CreateProcessAsUser API to launch the app from the toolbar. As a test program we use Windows notepad and use the explicit path to the app. The error we get back from the CreateProcessAsUser call is "The system cannot find the path specified."

Has anyone dealt with this problem before?
Any suggestions or help would be greatly appreciated.
