Scheduled Tasks

I have a domain service account that is used to manage some task on a particular server. I have the server added to a resource group, and the group has been added to the "associate resources groups for...." area of the domain account. However, when I change the password for the domain account, it doesn't appear to affect the schedule task. The "scheduled tasks status" is blank, and if I try to fetch, it doesn't find it.

I have a similar setup for another account, and that is working fine.

All necessary services are started on the server in question, and network connectivity has been tested, and there are no issues there either. This was working a few months ago, and no changes have been made.
