Hi, I have another problem: On our servers I get the event id: 10 Source:Citrix Resource Management : Resource Manager failed to compact its local database. If this problem continues and the local database grows to a large size, the administrator may have to compact the database manually using Microsoft Windows' Data Sources (ODBC) tool (found in Control Panel, Administrative Tools). Error: COMPACT_DB="O:\Program Files\Citrix\Citrix Resource Manager\LocalDB\\RMLocalDatabase.mdb" "O:\Program Files\Citrix\Citrix Resource Manager\LocalDB\\RMLocalDatabase.mdb" General. This occurs on servers which are upgraded from - PS 4.0 to 4.5 and - fresh installed PS 4.5 servers I know that the administrator could compact the DB manually - but why it this not be done automaticall? Any ideas ? Michael
