Win2k3 Server. Firewall on = no internet for workstations

[TriedandTested]

Is there a particular port that needs opening. If the firewall is on then the workstations don't get internet access.

Thanks.

Is it a DC?

If so then quite likely
DNS (most likely why users can't browse the internet)
Kerberos
LDAP
RPC and Netbios...
+some other less important ones will be needed.

what's the role of the server?
