You're running Sharepoint Portal Server inside your SBS domain and exposing it to the "world"?
You won't find anyone here supporting the opening of port 80 being passed inside the LAN...huge security hole

Thanks for the reply.
The main reason for activating the second NIC is to resolve some trouble we
are having with Sharepoint. Previously we had been using port translation at
the firewall to move incoming HTTP (port 80) connections on our Sharepoint
public IP to the different port used for Sharepoint on the LAN.
This was causing some performance issues and minor glitches, so we decided
to try putting Sharepoint on port 80 locally, using the second NICs IP
address (port 80 is already in use on the primary NIC). While it seems to
have cleared up our Sharepoint performance troubles, it has introduced these
new DNS and GPO problems.
Would these issue be resolved if I were to put the NIC on a completely
different network segment (192.172.x.x rather than 10.x.x.x for example?).
Locally, Sharepoint can still be accessed on the primary NIC through its
default port.

Unless this one of those unique load balancing nics that has software so
that it sees both wires as the same connection...this wont work
The second nic scenario is for the implementation of NAT or ISA
What issues are you seeing at 100mb?
How many users?
What kind of applications are in use?
