After applying hotfix form KB948109 the reporting services fails to start and logs theses 2 entries to event viewer:
The SQL Server Reporting Services (MS$DPM2007$) service failed to start due to the following error:
The service did not respond to the start or control request in a timely fashion.
Timeout (30000 milliseconds) waiting for the SQL Server Reporting Services (MS$DPM2007$) service to connect.
This happens even with a manual command for the service to start.
This happened in 2 servers and if we uninstall the hotfix the service returns to normal.
