Toddler Night Terrors?

Two nights ago my 2yr old, who has always slept solid through the night, suddenly changed sleep patterns. He now wakes up every 1-2hrs, sits up in bed, and screams. He doesn't acknowledge us when we calm him down, even if we try to yell so he hears us over the screaming. We have to turn the light on and stand him on his feet to snap him out of it.

I think it's night terrors. Any advice on easing it for him? We're all exhausted.
