Reported problems after installing Update Rollup 2 for DPM 2012 R2

Today I saw several users having problems with their Data Protection Manager 2012 R2 Server after installing KB2958100 which is the specific update for DPM in Update Rollup 2.

My advice is to postpone the DPM update and allow Microsoft to look into the user reports. Correction is quite complex and requires modifications in the DPM database.

See the thread for more details:
