Encounter Error when trying to inspect VHD

Question

Hi Hyper V Guru,
I am trying to do inspect on the disk of my VM by right clicking the VM-> select settings -> Select Hard Drive -> and click on the Inspect. However I am encountering the error message: "An Error occurred attempting to connect to the
virtual disk management service on computer 'localhost'. Cannot connect to the RPC service on computer 'localhost'. make sure your RPC service is running. what is actually the issue that happen?
Second query: how do I accurately confirm that my VM has no snapshot?
Third Query: if my disk is fixed vhd disk, is it possible to expand it? what are the best procedures and steps of doing this task? what I should notice properly before expanding? will there be any risk of expanding VHD? as this is our production
exchange server and very critical, I am really worry of doing this.
Thanks for your attention.
Regards,
Henry

Hi Henry,
I assume that you are using server 2012/r2 .
Are you using RSAT to do Inspect disk ?
If yes , here is a similar thread :

“ Second query: how do I accurately confirm that my VM has no snapshot? ”
Using the cmdlet : 
get-vmsnapshot  -vmname <the name of your vm >
