update:
DELL changed the working process from WMS 3.3.x with SYSTEM permissions to WMS 3.5 with an system account. I’ve create an system local account during the installation and everything was fine till the next reboot. The user is not assigned to the system local group “Log on as a Service and Batch” and the services can’t be started. So I added the local account to the local group.
I don’t understand why people do this. It’s a step backwards and makes it harder to work with group policies and hardening.
