Do you allow your Mac to go into Sleep mode when powered?
The reason I ask is because when my MBP goes into sleep mode I can no longer access it from my Apple TV (3rd gen).
My current setup. Late 2010 13" MBP sits vertically on my desk using a Twelve South BookArc so it is closed and powered. I have my MBP connected to a ASUS 24" PA246 via a mini display port to display port cable.
Now i think I could just change the Energy Saver settings for going to sleep to never when connected to power but is it ok to have it not go to sleep for long periods of time?
Doesn't the wake for network access work like I think it should? When it is a sleep and I try and access my mac or iTunes from my Apple TV should it not wake up? I have it plugged in via ethernet cable right now.

I don't know the technical answer but if it's a MBP I suspect it's because the WiFi is technically 'off' when it's asleep - if you were plugged into an ethernet cable that might work but the WiFi won't turn on I don't think.
If it's any consolation, we have an iMac plugged into an ethernet cable on the same network that the appleTV is plugged into (by cable) and it's hit and miss about 'wake for network activity', too.
The "wake for network access" checkbox controls whether the Ethernet/AirPort port responds to the magic/WOL/Wake-On-Lan packet. What i-rui is referring to is the Bonjour Sleep Proxy, which requires a recent Mac and AirPort Express/Extreme to send the WOL packet when network access to the device is requested.
Apple has a pretty decent KB Article discussing the technology.

OK I found this out. When I shut off my monitor my MBP it seems is going to sleep even though I have changed my Energy Saving settings to never go to sleep when powered. The reason I know it goes to sleep is when I shut off the monitor I can't access my library form my Apple TV but as soon as I turn the monitor back on and hit a key on the keyboard the mac wakes up and I have access on my Apple TV.
Just my own approach. Desktop Computer is put to sleep manually after either logging out or saving any files I care about. Why take chances?
Laptops never put to sleep, as weak batteries can really complicate the wake up call.
I do not enable network or admin access for sleeping computers, but again I never have need to do remote access. Tend to run the periodic commands at my convenience rather than when the OS schedules them, so that too is not a consideration.
If I am walking away for any length of time I shut down. I really do not buy into either argument as to benefits of never or always shutting down. This is just the way I like to handle things.
Obviously I am also not trying to use either unit to control other things.

If it is of any use to you, the Powerbook G4 1.67 I am typing on now is occasionally used to stream audio, and/or video in live situations. Hence it is set never to go to sleep, neither to switch on a screen saver, neither to have the hard drive sleep.
If I want to put it to sleep, I do that manually. If I leave it alone for a while, mostly I just turn the backlighting off.
Also, I make sure Little Snitch is not running, and Airport is switched off.
That is what I call "presenter mode".
This has not caused any harm to the brave old little beast at all, and you can pretty well guess how really old it is by now!
