Check if offline files are being synced

Check if offline files are being synced

I have been trying to find a tool or a script that can automate a check to
see what users machines are making an offline cache.
Basically we want to know that all the machines on our network are making
offline copies of the users designated "homedrives" this being where they
can store all of their work files. Is there a tool, VBscript or command
line script that we can run to check that the files are always available
offline for the users rather than having to go to 150 users machines and
going to the Sync center and checking they have a sync setup
