Time Machine Interesting Find for not working

[jmcgeejr]

I did some testing with a few PCs I have here at the office with OSX and I found that the ones that I couldn't get time machine to work were ones that didn't have a working nic during installation of OSX. Now if I installed it with a NIC and then swapped out that nic for another one it wouldn't work until I deleted the network pref file but then it would work again. However no matter what I did if I installed OSX and it didn't see a NIC during install it would never work. Just something that I noticed. Hope it helps those of you with these issues.
