Give me back 3.6 please

The new update is atrocious. I am in a school environment with over 400 macs and when i do a network range scan it returns 5-10 machines. The rest show authenticating, offline, or access denied. If i scan 2 minutes later ill get a different 5 machines and the ones that showed up last time are now offline. Even if it says access denied i can still observe the screen i just cant copy files or install programs. Please give up on 3.7 and give us back 3.6 it worked so well!!
