We have the following infrastructure:
- An IIS WebServer with Visual Cron Server installed on it.

We want to be able to start Visual Cron task via WebServices or via some Web Application (C# / .Net)

It's really easy, you just have to use the visualcron API ... and then ... it does not work unless: The Application pool (IIS) running the WebSite/WebService must have Local User privilege rights (Or domain user if you have a server farm)

By default IIS Application pool does not have Local user right, and by default you will have some strange Null Reference exception.

I know it's not directly linked to the usage of the API but it may help someone to read this... we searched for 4 days before figuring out that it was linked with privileges.

Have you tried connecting locally with the Remote connection type to see if that makes a difference? Also, have you tried to turn off logging in the API?

Yes we had to turn off logging. But with our infrastructure we have to connect remotely (we have a farm of server).

So, it is working now after turning the logging off?
