Remotely delete cache?

I was wondering how to remotely delete cache on a workstation. I have from time to time had a client workstation where clearing the cache has resolve bundle deployment issues. right now I psexec into the system and run: rmdir "C:\Program Files\novell\zenworks\cache\zmd" /q /s

Wasn't sure if this is the only way since zac cc reports a permissions error.

The other question I haven't found an answer to is whether a way exist to clean up post deployment items after Installations.

Thanks for the help.
