A few days ago I installed Windows Server 2008 R2 on a new Supermicro server with dual XEON processors and 12 GB's of memory. The motherboard has two Intel 82576 dual port gb NIC's. But the throughput between this new computer and other computers on the network is very slow. Files transfer at about 3 mbps rather than the 55 mbps that other computers on the same switch and router are getting. Any help would be greatly appreciated.
