Hi,
To see additional information about the task instance processing on a remote task server please add the next registry keys on the corresponding site-server:
1. Create registry branch: [HKEY_LOCAL_MACHINE\SOFTWARE\Altiris\TaskManagement\Logging]
2. add Dword keys (set 1 as a value): TaskExecution, BaseClientTaskReporting, InstanceStateKeeperEngine
As I understood, you are on 7.5.SP1 code, so you do not need to restart any service, just wait for 1 minute (with 7.5 you should restart atrshost service after keys were added).
Now, if you will run task to some client and such client assigned to Task Server with additional logging turned-on, then you should see detailed task processing events in task server log, like:
=================
(Start) starting task instance 'MyTask' (46cd8e46-0f63-452f-bcd5-b992f23dab24), thread=48304161 (20)
Execute task instance 46cd8e46-0f63-452f-bcd5-b992f23dab24 on resource 539fac8f-69fb-46f6-a9ce-54edc404b645
(Sent) task sent to client: 46cd8e46-0f63-452f-bcd5-b992f23dab24, resource=539fac8f-69fb-46f6-a9ce-54edc404b645, reseting timeout to 7/31/2014 12:25:08 PM
Task instance ac8dc58e-3cf6-4967-b9ef-de0898bfefeb is successfully with return value: 0
=================
"MyTask" is a task name in NS console.
Thank you,
Alex.
