Computer SCCM client lists "No Results" for
"Client Check Result" in the System Center 2012 Console
Problem: SCCM client computer listed as "no
results" for "client check result" in the system center 2012
console client monitor. You'll notice on the problem computer that it's missing
the ccmeval.log and you'll see errors in the ccmevaltask.log file.
The ccmeval.exe is run from a scheduled task that is created
upon installation of the agent. This task is run daily to allow the computer to
check-in with the sccm server. More than likely this error condition occurs
when a client agent was upgraded, but for some reason the scheduled task wasn’t
recreated. On the problem computer you'll see listed under the task results
"not registered" or other failure codes.
Solution 1: On the computer with the problem client, in
Task Scheduler under Configuration Manager folder in the Microsoft folder,
right click and Run the task Configuration Manager Health Evaluation. Refresh page, and verify task updates to show
“Last Run Time” as the current time (when the task was Run).
If this doesn't fix the issue, try solution 2 below (from Dale's Tech Blog).
Try Solution 2: On
the computer with the problem client open the Task Scheduler in Control Panel.
Open Microsoft folder in the Task Scheduler Library, then Configuration Manager
and delete all listed entries. Initiate the “install client” with the “always
install” option checked from within the SCCM 2012 console. The scheduled tasks
should be recreated when the agent installs and the computer will start
checking in appropriately to the SCCM server. Check the local computers
ccmeval.log file for more details.
After implementing one of the above solutions, prompt the
client to check in with the SCCM server by running that client’s Data Discovery
Collection Cycle either by opening from Control Panel > Configuration
Manager, go to Actions Tab, and selecting and running the task, or using Right
Click Tools, if installed, in the SCCM console.
Tip: Open up the Task Scheduler by either typing "task" into
the Start Menu search bar, or by opening All Programs > Accessories > System Tools OR go to Control
Panel > Administrative Tools
