SharePoint Timer Service not starting due to a logon failure

Hello everyone,

SharePoint Timer Service on my SharePoint Web Server stops by itself every couple of days or so. Trying to restart it gives me the following error:

Windows could not start the SharePoint 2010 Timer service on Local Computer.

Error 1069: The service did not start due to a logon failure.

I am able to start it after retyping the SP Service Account password. SP Service Account has Administrative rights to the machine. There are other services with the same logon, Web Analytics Service being one of them, that don't display the same behaviour.

I am not sure if this is an Active Directory issue.

Has anyone experienced this condition?

Regards,
