Hello Harmjan,
You have choosen the badest option for configuring a DC. Multihoming creates
lot's of problems. Also ICS on a DC is not optimal. Disable it.
Connect all machines to a switch and also the server with only one NIC or
use teaming if it is supported form the hardware vendor. Then connect the
switch to the router. The other NIC of the DC disable. Then configure the
FORWARDERS tab under the DNS server properties in the DNS management console
to the ISP's DNS server.
Best regards
Meinolf Weber
