It is not possible to start the DocuWare Applications Pools in the IIS or rather they stop immediately again.
In the windows event viewer you will find the following error:

"Windows Process Activation Service (WAS) encountered a failure when it started a worker process to serve the application pool"

This behavior occurs because of missing rights for the windows user, which is assigned to the DocuWare Application Pools in IIS. The Windows user needs the right "Log on as a batch job".
