All of a sudden, report doesn´t work anymore

Question

Getting really tired of this whole SCOM-thing the last days.
Now the reporting doesn´t work anymore. We changed NOTHING.
State went from Zero to Healthy 4:14 PM on friday last week. Alright.
But a few hours later, when nobody was here anymore, it changed to EROR.
How can that happen?
Reports are EMPTY suddenly. You can't start report-tasks anymore. They disappeared.
We checked:
- Discovered Inventory -> Data Warehouse Synchronization Server
- State is Critical.
- Display name is wild numbers+characters, is this normal?
- Health explorer says:
'DeploymentException': Failed to deploy reports for management pack with version
dependent id '471cffe4-2085-cf71-2513-ecbac52be31f'. Failed to deploy report

Hi,
Generally these errors are caused by improper SQL SRS configuration, to confirm SRS is initialized correctly, are you able to navigate to http://localhost/reports or http://localhost/reportserver?
Are you upgraded to SP1 RC yet and have you the latest versions of the MP' as a lot of these reporting issues have been resolved?
Also re-check all your SRS accounts have the relevant permissions and all permissions in IIS are correct?
You could try resetting the SRS configuration and re-install Reporting.
1. COPY the ResetSRS.exe file in SupportTools folder of the OM 2007 media to
C:.
2. Open a Command Prompt and change your path to C:.
3. Type "ResetSRS.exe  MSSQLSERVER" where MSSQLSERVER is your SQL instance
name.
4. Then open Reporting Services Configuration Console, select Web Service
Identity and click Apply.
5. Finally, reinstall your reporting service by running OMSetup.exe again.
In addition, please provice the event ID under event vierwers, so that we could analyze it further.
