Alan,
I don't know if this helps or not. We have a fairly large network and what we did was hard code all the servers and switches in our data center but in the field we let everything auto negotiate. Then what I do is monitor for FCS errors (via SNMP OID) on our switches, in the data center and throughout our network, to see if we have a duplex/speed mismatch. I'm using Webnm thresholds to do this which pages and emails us when a port starts logging FCS errors and then we can take corrective action. In our data center we have quite a few SUN servers and even though we constantly remind our administrators about hard coding the NIC speed and duplex to match the switch you would be surprised at how many times it gets set incorrectly on SUN servers, but we get the page and email very quickly, when the FCS errors start occurring, and we are able to address the problem before people start complaining about how slow applications and such are running.
Take care,
Alan

Are there any utilities out there that will tell you what a workstations actual network connection is? I know you can turn on the icon and see if it is 10mb or 100mb, but I also want to know if it is half or full duplex. Currently we have most of our equipment using auto both on our switches and end nodes, but I keep seeing that it can be mis-reported and that everything should be hard set. A little more maintenance involved, but better performance in the long run.
Thanks
