Question : DNS does not forward requests

Greetings from Athnes, Greece and my best wishes for a happy new year.

Here is my problem:

I have a Windows 2000 Server, running AD,DHCP and DNS. Last week I set up a Broadband connection for the company (ADSL).
I setup the DNS to forward requests to ISP's DNS servers but it doesn't seem to work.
Now I only have the workstations with internet acces by adding the ip for the DNS servers of the ISP in DHCP scope option for DNS (006). I know this is the wrong way but it was the only one to give the clients internet access.
If i ping from server an IP, I'm getting replies, but pinging by name or trying nslookup has no effect.
Here is  a description of the setup.

Domain Controller:
IP : 192.168.0.200
DHCP : no
DNS : 192.168.0.200
Default Gateway : 192.168.0.254 (ADSL Router's IP)

Clients:
IP : Dynamic
DHCP : Yes
DNS: 192.168.0.200
         195.170.0.1 (ISP'S primary DNS)
         195.170.2.2 (ISP's alternate DNS)
Default Gateway : 192.168.0.254 (ADSL Router's IP)

Clients resolve exterlan names to IP only if i ad the IP of the ISP's DNS (i.e. nslookup www.yahoo.com 195.170.0.1).
Otherwise they do not...

The server does not resolve external names with or without ISP's DNS

Any help ?

Answer : DNS does not forward requests

Sounds correct but it still problem points to this box, try to delete this configuration and reconfigure see if it resolves.
