Default Gateway with Token-Ring

[Wayne Moore_1]

We have a series 800 server running 10.20. It is currently running IP using the integrated ethernet NIC. We want to add a Token Ring NIC for SNA connectivity via DLC. When we add the system to the ring, the default gateway changes to "localhost" and when we try to change it, it gives an error that states "entry in use" We are unable to ping outside of the subnet unless we disconnect the cable from the NIC. We do not want to use IP on the token-ring, only DLC. How do I change the bindings?
