I'd do/check the following:

1. Is auto-negotiation active on g1? If yes, turn it on on g0 too.

2. What happens if you switch the network cables (from g1 to g0 and from g0 to g1).
Does g0 become 1000 Mbps? Does g1 become 100 Mbps only?
If both assumptions are true, then plug both cables back as it was before.
Now you can exclude the problem on the server side!

Start troubleshooting on the switch side, e.g. compare the configuration of the switch ports, where the g0 and g1 network cables are plugged in. It's possible, that the switch port, where the cable from g0 is plugged in, is configured for 100 Mbps only.

Hope this helps.

Exactly. There's a physical problem with the link that won't autonegotiate. If you're lucky, there's a good chance someone disabled autonegotiation on the switch side and pinned that switch port to 100fdx.

Again: disabling autonegotiation is bad. If a link won't autonegotiate the highest speed it's supposed to, SOMETHING IS WRONG. If a car gets a flat tire and doesn't handle well, you don't ignore it and just force it to continue going 120 kph/90 mph. You fix the flat.
