To resolve this issue:
1. Stop the Core service as well as the SQL server service on the Core.
2. Set the log on account for the SQL server service to a local or domain administrator.
3. Start the SQL server service and create a new user. Give the new user account as sysadmin role security permission.
4. Start the Core service,
5. On the Core console, access the agent’s Summary tab, set the SQL credentials to use the new user account and set it to Windows login instead of SQL.
