Symantec Endpoint Protection Manager (SEPM) installation is corrupted and it needs to be reinstalled and connected to existing SQL database.
Symptoms indicating a corrupted SEPM install include but are not limited to: SEPM failure to deploy content/definitions to the clients.
This solution consists of collecting the SEPM configuration/communication settings per the Disaster recovery document, uninstalling the current SEPM install and reinstalling it. This process will result in a clean install of the SEPM, utilizing the current settings to maintain communications with the SQL server and the SEP clients. This process will retain the current SEPM/DB content, such as policies and definitions.
