Double and triple checking didn't make it any better... Network and Security are not showing up.
After some searching I thought maybe this was because I was running Backup Exec 11d Quickstart. But after a little more digging, I found that wasn't it at all. It was simply a preference setting.
So back in options, I went to settings like so:
And at the bottom of this screen there is a radial button that was on 'Simple' instead of 'Full'
So I changed that to full and confirmed out. And would you look at that, Network and Security is there!
I don't know if anyone uses backup exec 11d anymore, but if you do, I hope this was useful :)
