EEK - I need networking HELP QUICK

Hi Guys:

I need some STUPID help...

We switched ISPs today, and I need some help...  

We're running Windows 2000 domain controllers, and since switching over to the new ISP, and utilizing our SonicWall for our firewall, we can't connect to the domain controllers.  It's a WEIRD problem, I can ping the domain controllers, but I can't connect to them.  I tried adding a pc to the domain, and I get an error saying the pc cannot locate a domain controller.  EEK, what to do?

well I can log onto the machines, but that's just cached...
have u just stated using sonicwall?
yes, I JUST started using it...
So you never have used the connect WITH firewall ... you should better give us an overview of your network setup, so we better know, where the firewall comes in etc.
it's a simple switched network.

cisco 2600 -->  sonicwall pro 3060 --> domain controllers --> pcs&printers
I know it's a stupid problem...  My SonicWall has our ISPs DNS server registered, so, the clients are pointing to it for DNS, and it's pointing to the ISP.  
shouldnt the clients point to the dns on the domain controllers and then the domain controllers have the isps dns as forwarders. Your ISPs DNS wont know the ips of your domain controllers.
