First try it with WBEMTEST to see what is going with the WMI class. The error you are getting usually means WMI misses that class and you should load the mof again/ maybe rebuild the entire repository (careful as the windows files are all located
on 1 folder, but applications tend to store it in their own folders, like citrix, ibm, etc).
Try to run this command:
mofcomp "<Programfiles>\Citrix\System32\Citrix\WMI\ .Mof file for citrix"
{citrixProv.XP10FR3.mof, metaframeProv.XP10FR3.mof, and mgmt.XP10FR4.mof files}
Then, run the WBEMTest again and the namespace should be returned successfully. Then restarting the health service on agent.
