Multiserver administration - passing maintenance plans to clustered instances
JohnnyP.
I know that a long time has passed - but maybe someone will need it.
This error is related to the sys.dm_os_enumerate_filesystem() function launched without the @Path parameter.
In my case, the error appeared due to the fact that I did not specify the folder for the job execution log.
If you create a maintenance plan by wizard, then you need to tick  the 'write and report to a text file' and select folder on the &quot;Select Report Options&quot; window.
