See the following steps to enable logging on a roll-up core.
1. Find the shortcut for the LANDesk Rollup Database and add the path of the shortcut to the start in path (environment variables). I.E. "C:\Program Files\LANDesk\ManagementSuite"
2. Open a registry editor
3. Add a dword value 'rollup log' under HKLM\Software\LANDesk\ManagementSuite\Core and set the value to 1
4. Close the Rollup Utility if it is open.
5. Open the Rollup Utility and roll-up the database. If an error occurs, see the log file in folder that is the same as the shortcut for the Rollup Utility--in our case C:\Program Files\LANDesk\ManagementSuite. The log file will be named rollup_linkname.log
