Home sharing has not worked for me since the upgrade to iTunes 11.
Sandancer:
I had this happen once on an iTunes upgrade - not sure why but iTS upgrades DO seem to confuse ATVs occassionally.
Some Options:
If you have another home share device, try connecting to that first.
One other thing that worked was a total reset. Then I followed Apple's instructions as if I was setting up for the first time. The counterintuitive part was that iTunes needs NOT running when you first enter info in ATV. THEN atv gives you a code to enter. At that point you open iTunes. (truly bass ackwards). Don't recall if I tried, disabling then enabling Home Sharing on the computer.
Anyway, don't dismay. iTunes 11 DOES work with ATV.
You should also look at the following article which discusses port settings for iTunes, ATV etc.:
