Workflow

Every-time we try to run a business process it display's this error message, wondering what is happening, you can run the workflow fine from the designer or trigger it by certain move/create etc. actions, but does not want to run by right click start business process. One process that used to work when we were on 9.1 has also stopped working and same error message. Any ideas what is this error about ?

Error Code: 0
Error Message: Error launching Business Process:

Go to the web server where the Workflow Web Service is installed. In IIS, view the authentication settings for the Workflow web application and enable Windows Authentication. Anonymous Authentication may already be enabled by default which is fine. Restart IIS and then republish the business processes in the Workflow Designer. Now log out and log back into the Laserfiche Client and see if you can start a business process.

I am not sure why it was working without windows authentication cause that role/feature for IIS was never enabled on that server, but it worked before. Well to fix this I ran the configuration manager for workflow and it right away poped up a window saying the configuration for "workflow web services" needed to be set to default authentication (or something like that). Doing that and restarted the vm, fixed the issue at hand.

Any ideas what would have caused configuration to change ?

Sorry for the late reply. The authentication for the web service used to be set to anonymous in Workflow 9.0. It has changed to Windows Authentication for 9.1 and higher.

We have a Forms server on the DMZ that needs to start workflows inside the network. The DMZ is not part of the internal domain, so Windows Authentication is out of the question: the Forms server will not be able to authenticate to the Workflow web service with that method. So we keep getting these error messages whenever Forms reaches that step in the process.

Can we enable anonymous authentication for the Workflow web service to get this to work?

Edit: I tried it and it worked. We'll add this to our internal documentation.

You should use IP filtering in IIS to restrict access to the WF web service to only the Forms server since the web service is now open to the internet.

I am getting same error on 10.3.1 and confirmed that Windows Authentication is enabled per Alex's 2/4/15 post. Looking for some thoughts on additional triage, thanks.
