I was trying to look for some tutorials or books that might help with NetIQ Aegis but I haven't been able to find anything.
I created a small little Workflow. Had a user click start or stop. If started the process would go grab a file from a directory on a machine and then e-mail user X with the file and then end. Works fine but it's very simple.
Then I created another Workflow, this one also had a start and stop. If started it would go to said machine delete a registry key from a certain directory, e-mail user x if the directory registry key had been deleted and then end. The Workflow completes, no errors show up but the registry key is never actually deleted. When the process runs it runs with domain admins rights. So not sure what I might be missing.
It sounds like there is an input or output to an activity in your workflow that is causing the problems and unfortunately, without being able to see the workflow and the details of the activities, there's not a lot that I can help with. You mentioned that there were also some email activities - Do you receive the emails at the right times with the right content?
