What steps should I take if the Agent's logon account is the problem in Error 1068?

Verify the logon account's password, if it's a domain account. If it's a local account, ensure it has the necessary permissions. Try changing the account to a built-in system account (e.g., Local System) as a test and see if it starts. If the account is the issue, the Event Viewer will likely contain account-related errors.
