Scenario:
NW65SP3
NAMED.NLM v6.04.10

Issue:
Ping cannot resolve DNS-names from server consoles

Details:
One small NDS-tree, all servers NW65SP3.
One single server runs both DHCP/DNS.

DHCP and DNS works well from the PC's in all LAN subnets.
Resolving via ping also works well at the DNS-server console itself.
But pinging a DNS-name fails from all the other server consoles.
Neither local server names in the same DNS-zone (and same LAN subnet),
nor internet web adresses resolves.

Resolv.cfg deleted and recreated correctly via Inetcfg on all servers.
IP-helpers in place in all switches, no firewall denial logged either.

Ideas?
