Problem

After upgrade ESXi and Reboot ESXi Host Server, ICM Diagnostic Portico is unable to show ICM services or processes.

Diagnostic portico logs show the following error message:

"List Services Error: Exception while getting the service: Invalid Class" "No ICM services available"

Troubleshoot

Step 1. Diagnostic portico has dependency on Windows Management Instrumentation (WMI) to

             function  properly.  WMI service needs to be checked  if it is functioning properly.

Step 2. Go to  Windows application and system event viewer logs

            Check if there is any group policy applied that is impacting WMI service .

Step 3.  In ICM windows server,  go to 'Start' >'Run' and Type 'mmc' .  

             Once the console is opened , click  'Add/Remove Snap-in' >  'Add WMI' , then click 'OK'

Step 4.  From left side pane, right click 'WMI Control'  then click 'preoperties'.

             if WMI properties are successfully seen , then WMI service is working fine .

             if recevied an error , as shown in the image , then most likely WMI service is corrupt and needs to be rebuild.

Error: Failed to initialize all required WMI classes.

Win32_Processor WMI: Invalid class

Win32_WMISetting WMI: Invalid class

Security information: Successful 
Win32_OperatingSystem WMI: Invalid class

Solution

Step 1. Verify 'DiagFwSvc' Type , the Value needs to be '0x0000110 (272)'

            Register key path :

HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > services >DiagFwSvc

           verify  Type is set to '0x0000110 (272)'.

           If not , need set the Type value to '0x0000110 (272)' , stop WMI service and start it.

           If this does not fix the issue , then proceed with solution setp 2.

Step 2. Rebuild Windows server WMI service.

           Here are some basic guidelines to repair the WMI which  strongly recommend to engage

           windows system administrator for completing below steps to rebuild the WMI service. 

a. Disable and stop the WMI service.

1. Go to windows command prompt and type:

sc config winmgmt start= disabled

2. Then, type:

net stop winmgmt

b. Run the following commands from windows command prompt:

Winmgmt /salvagerepository %windir%\System32\wbem

Winmgmt /resetrepository %windir%\System32\wbem

c. Re-enable  WMI service from windows services and set the Startup type to 'Automatic'

d.  reboot the windows server
