Hi Rob,
This blog post answers a similar question that I had. In my case, I am trying to integrate legacy applications into a clustered server environment. The existing UI is integral to monitoring and troubleshooting the application. Seeing as how the ability to interact with the desktop has been removed, I may have to write a custom resource DLL that can independently launch the legacy applications.
In the meantime then, my question becomes whether it is possible to launch generic applications under a separate domain user account, or must it run under the Cluster's local system account?
Thanks,
-Mike
