The 1Gb speed is on an autonegotiate setting. The full duplex setting says 100 Mb. Why isn't there a 1Gb full duplex mode?

I also am going to update all the drivers and firmware on the server that has been a sluggish performer. It could be that it was just network issues, but better get everything out of the way.

Would setting the VOIP phones to a VLan help out? Or would it be just as good to set them to low priority in QoS? Once again thanks for all the help and if you can think of anything else that can really streamline a network let me know.

Does anyone have a recommended switch that is good for large amounts of traffic/data and works well under heavy loads. Currently we have a mixed bag of 3com superstack switches, Netgear smart switch, Dell unmanaged/webmanaged switch, and some PoE switches for the VOIP phones. Perhaps someone knows of a good way to set these up for best performance.
