Microsoft PsTools is an important prerequisite for configuring Internal Loggin in CA Service Desk.
If PsTools is not properly installed and configured, options like "Task List" will not work as expected.
CA Service Desk Manager 17.1 and higher.
Instructions for installing and configuring Microsoft PsTools:
Known Issue: If you do not run this exact command, and Interval Logging is not able to run pslist successfully. It can result in two "locked" pslist commands in the Task List. If it happens with you, kill them manually.
Somehow it got locked because of not accepting the license agreement.
Consider restarting all SDM services and make sure there is no remaining JAVA process running for Interval Logging.
