How can I resolve "Error 1069" when a Windows service fails to start?

To resolve Error 1069, follow these general steps: 1. **Verify Credentials:** Open Services (services.msc), locate the affected service, right-click, select Properties, go to the "Log On" tab. Re-enter the password for the specified user account (and confirm it) to ensure it's correct. 2. **Check Account Status:** Ensure the service account is not locked out, disabled, or deleted in Active Directory Users and Computers (for domain accounts) or Local Users and Groups (for local accounts). 3. **Grant "Log on as a service" Right:** Ensure the service account has the "Log on as a service" right. This can be configured via Local Security Policy (secpol.msc) under Security Settings -> Local Policies -> User Rights Assignment, or via Group Policy for domain accounts. 4. **Restart System/Domain Controller:** If it's a domain account and there are network issues, restarting the machine or ensuring domain controllers are accessible might help.
