I have a farm with SharePoint 2010 integrated mode SSRS 2008 R2. A few days ago, one night at about 02:00 AM, almost all shared data source references had gone. I couldn't find any clue at neither SharePoint nor SSRS. I did create almost all report connection references manually but still don't know why they had gone.


I found this post and situations are similar but at my situation, nobody removed shared data source references or connections. They have just gone.

Is there anybody who knows the reason or gives me the insight of where to look at for further information?

  • anything in the SharePoint logs or SQL logs? – Shawn Feb 14 '19 at 0:17
  • Unfortunately, nothing in the logs :/ – newbie Feb 18 '19 at 5:43
  • was not there any installed update? – Zdeněk Vinduška Feb 18 '19 at 14:55
  • Nope :/ I'm looking for SQL Server Builds. It could be a bug :/ – newbie Feb 22 '19 at 6:20
