All client machines show a status of 'Not Reporting' inside the System Recovery Management Solution console. All client communication is working and scheduled backups are running.
This has been seen (but may not be limited to) following a re-installation of the Symantec Management Platform (SMP) and SSR-MS. The original database was re-attached to SMP following the new install.
Edit the CoreSettings file using notepad. CoreSettings is found in \ProgramData\Symantec\SMP\Settings.
Change the value of "EnableNSEventLog" from false to true and save the file.
Once the above has been done, restart the 'Altiris Service' on the SMP/SSR-MS server. Client machines will then start showing the correct status when they next send their configuration update (by default, this is set to once an hour).
