Networking problem with two Virtual Nics in a single vm

Source: microsoft.public.virtualserver

I have a problem with using 2 virtual nics in a single vm. I have two
physical nics installed in my physical host, each connecting to different
networks.

192.168.1.x and 172.14.8.x

The vms I created each have two virtual nics in them each connected to a
different network (as noted above). The second nic does not have a gateway
configured to avoid a multiple gateway problem (second gateway is not needed
as this nic only needs to communicate with servers on the same subnet). The
physical server can ping out on both subnets, and I can ping both IPs from my
workstation (a seperate vlan). The vms can only communicate over the
192.168.1.x subnet and not the 172.14.8.x subnet. The nic shows as connected
but there is no communication. I can not ping the second IP of the vm
(172.14.8.x), the first one is pingable (192.168.1.x). I have checked the
way the networks are configured within virtual server and the configs look to
be a match on both adapters. ie.

"Physical Nic 1" is on "External Network 1" which node a, b and c are
connected to on "virtual adapter 1"

"Physical Nic 2" is on "External Network 2" which node a, b and c are
connected to on "virtual adapter 2"

These are both configured as external networks.

Despite the like configurations one virtual adapter works in all the vms,
and one does not on all the vms.

Any help would be greatly appreciated.
