There were some machines where we saw SCCM client communications wasn’t
happening from last couple of months and the number was quite large. We had to
carry out the analysis for that and we have been asked to suggest the solutions
based on our findings, here’s what we found after analysing 40-50 odd machines.
Common errors found are as below
1. Errors in execmgr.log and rebootcoordinator.log Failed to instantiate UI Server with
error 80004005
2. Errors in certificate maintenance.log ‘CCMDoCertificateMaintenance()
failed (0x800703fa).’
3. Errors in WUAhandler.log ‘Failed to Add Update Source for
WUAgent of type and id Error = 0x8007000d.’ and 'Unable to read existing
resultant WUA policy. Error = 0x80070002' and 'Unable to read existing
resultant WUA policy. Error = 0x800703fa' and 'Group policy settings were
overwritten by a higher authority (Domain Controller) to: Server and Policy NOT
CONFIGURED'
4. Errors in updates handler.log ‘failed to download update Error
= 0x800705b4'
5. Errors in windowsupdate.log Failed to save WUAgent policy with
updated WSUS Server. Error = 0x80070070
6. Errors in updatesdeployment.log 'Failed to get message id in
failed progress state, error = 0x80040200' and 'Job error (0x80070070) received
for assignment ' and 'Execute- Failed at AddUpdateSource, error = 0x80070070'
7. Event viewer logs: The system has
rebooted without cleanly shutting down first. This error could be caused if the
system stopped responding, crashed, or lost power unexpectedly.
Hence it was apparent that the sccm
clients had issues and it was all pointing out towards software updates
components, my initial guess was that either machines were not rebooted after software updates installation
or they were force rebooted during the installation phase, hence we checked the
time stamps for reboot coordinator along with software updates deployment
schedules. We rebooted couple of machines and they started functioning
properly, we tried services restart which also worked on few machines, we then
found a hotfix for the above mentioned errors and deployed the same on some
machines which fixed the issue. Based on our finding and troubleshooting results
we suggested following
Suggested Solutions:
1. Reboot machine
2. Check if the machine reboot has
fixed the issue
3. If not restart services i.e. SMS
Agent Host, Windows update, WMI service
4. Run a script to reset windows
updates component and restart services
5. Check the logs and based on errors
try Installing hotfix:KB947821
6. Analyse the logs again and
initiate client repair if required
7. Analyse the results and take a
call on WMI repair if required
