Impact 2: Veeam Services Configured to Use Domain Account Fail to Start
After the machine is removed from the domain, any services associated with Veeam that were configured to 'Log on as' a domain account will fail to start.
The default configuration of Veeam Backup & Replication uses a self-deployed database engine, and the services are set to use the "Local System Account."
When customers have elected to host the Configuration Database remotely, and the services are set to use a domain account, that domain account will fail as the local machine can no longer validate the domain account. In such a situation, the services should be changed to "Local System Account," and the Database Configuration tool should be used to reconfigure Veeam Backup & Replication to connect to the remote database location using native authentication*.
*This would require that you have configured native authentication within the remote database engine software.
