Group policies not working in OU’s

I have two Domain Controllers in my win2k domain. I put two member servers in their own Organizational Unit. I apply a new group policy on that OU but it never takes. I have to go to each server locally and set the group policy. I had this working perfectly at a different office with only one Domain Controller and I’m doing the same thing here. Is there something different I have to do with two DC’s? I know their talking to each other because when I add a new user it shows on the other dc. Also, domain policies arent working either…I have to use Local policies on each server. It’s like their not participating in the domain, but I know they are. Users login to the domain fine.
