Unexpected switch at this level

Hi,

We seeing event 2213 on our server 2012 DC that has the 5 fsmo roles. we have 5 DC's in our  doamin, 2 in the same site and the rest in different site.

The event viewer says run this command:

wmic /namespace:\\root\microsoftdfs path dfsrVolumeConfig where volumeGuid="32D935BE-37DF-11E2-93E7-806E6F6E6963" call ResumeReplication

I did run this command from Powershell as admin and run the above command and get the message:

Unexpected switch at this level

Should I run the command from command prompt? or the above messge has other meaning?

Thanks

Shahin
