Hey Sukhoi,
Yes there is
Commandline options:
dnetc -update (fetches and flushes)
dnetc -fetch
dnetc -flush (these are obvious

)
dnetc -restart (obvious too isn't it?!?

)
dnetc -shutdown (again obvious)
Just make a shortcut and use the one you want and you should be fine

I don't remember if you need " " around the shortcut, but if it doesn't work without it'll work with
With love and respect your fellow TA member
