Factory Class Best Practices?

Does anyone have any suggestions about where to locate factory classes? I've got a bunch of static factory classes that I use to create other classes. I've put a lot of these into my common tier, in our Common.Util namespace. I just ran across a class that I can't put into my common tier, since it references a business tier object. So I've put it into my Business.UserAuthentication.Util namespace. But, now I'm thinking that a VIT.Business.Factories namespace may be best. Or should I locate these in a Util namespace for each assembly?

Factory classes should generally go in the same namespace/project as the classes they construct.

+1 for putting them in the same namespace/project as the classes they create.

I agree, but what if you cannot because of circular reference problems? Most of my factory created classes are in my Common tier.
