Just thinking,
but my boss is so slack he doesn’t back it up… he would rather not have the aggravation
I’d be tempted to download some donkey porn onto his desktop, then when he kicks off suggest that it could be a hack attempt / virus which is a result of his cavalier attitude to security.
Alternatively, if he doesn’t give a toss, why should you? Let it grind to a halt, start a few big downloads going to help it along, then when all the users complain tell them it’s because they’re using spotify.
I miss my internal sysadmin days, they were fun.
