While smacking my pack of Wyeast pitchable, (1084) I created a hole in it. So as I type this, I started a starter form dried extract. I hope 10 minutes is a long enough boil for a starter. Is it? I have had troubles with contamination so I have been using dry yeast for the past 6 batches.
So the questions I want answers to be, how long do you need to boil dried extract when making starters?

I usually boil starters for 15 minutes. Just what I was told by experienced brewers when I started.

A couple of years ago I talked to a guy at Wyeast (I think his name was David), and he recommended a 20 minute boil when using DME- so that's what I have always done.

Ted, when using DME, all you're really trying to accomplish is to completely dissolve it and to sanitize it. You won't get a substantial amount of hot break from it, because it's already been mashed and treated to hot temperatures during the drying process, so a prolonged boil is of questionable value. 10-15 minutes is quite sufficient, IMHO. Now, if you're making an pure extract beer, complete with hops and specialty grains, that complicates the chemistry quite a bit, but for starter purposes, I'll stick to my 10-15 minute guns.
There have been a number of articles in the recent past on this topic in various publications. BYO comes to mind; I think they did a feature comparing various extract boil strategies recently.

any bacterial organism that can survive a 10 minute boil is welcomed to infect my beer.
i worry more about the lip on the pot's rim where i pour out the contents. i scrub this area with 99.9% isopropyl alcohol 2 or 3 times and ignite it each time.

I do a 10 minute boil. I used to do 15-20 min., but I haven't seen any difference between that and 10, so now I save myself the extra 10 min.
LIfe begins at 60...1.060, that is.

I do 15 min with extract starter. No problems that I know of. Anyone do 13 or 17 min?

15 minutes for me, then into a kitchen sink full of ice for a quick cool. I never worry about the lip of the pot, I figure it gets too hot for anything to survive there.

Grahams explanation works for me. 10 minutes and I also don't worry about the lip of the pot.

8-10 minutes here. Any more seems like a waste.

8 minutes if I'm doing a liquid yeast starter.
If I'm rehydrating dry yeast, I put 250 ml of water in a 1000ml Erlenmeyer flask with about a tablespoon of DME and nuke it in the microwave for 4 minutes. Cool it to about 80 degrees, sprinkle the yeast in, and watch it explode! (figuratively)

I guess I can cut it down from 20 min to 10 for my starters. I always thought 20 was the norm ! You never stop learning...
As to the lip of the pot, I agree that it probably gets hot enough to kill any nasties. It's the lip of my starter vessel (1-2 days later) that I'm concerned about. I always flame the lip before dumping into the fermenter.
