Hi @Franz Schenk ,
Thanks @Gath very much for your help. We're glad that the issue is gone now. It's appreciated that you could click "Accept Answer" to the helpful reply, this will help other users to search for useful information more quickly. Here's a short summary for the problem.
When trying to open any report, reporting services crash with the Logon failure: the user has not been granted the requested logon type at this computer.
Some security people have applied the Microsoft Member Server Security Baseline GPO. In this GPO, only the group "Administrators" has the right to log on locally. Disabling the link to this GPO makes SCCM reporting working.
Thanks again for your time. Have a nice day!
