10/100/1000 ethernet over 2 pair wiring

I am troubleshooting a server to clients connectivity issue. I have changed all patch cords and swapped the rj45 jacks. I have not tried installing a new NIC in the server as of yet. However, I did discover today that the cat5 cables at the 12 port patch panel only have the orange and green pairs punched down as per 100 base tx. I wonder if anyone has run into any intermittent connectivity issues when running Gig E on only 2 pair 100 base tx.

Thanks shalvors. I know that GigE requires all 4 pairs, and that 10/100/1000 hardware should throttle down to 100 BaseT if only 2 pairs are present. I was wondering if anyone has experienced or heard of dropped connection issues when running GigE hardware on 2 pair 100 BaseT.
