I have several onboard nics with Dell optiplex, installed Windows xp. why is that sometimes the nic card is set for 100mb full duplex and not Auto negotiate. it will do this sometimes on some pc's then i have to manually change it to Auto?
I setup the computer months ago was fine until recently when the users phone which is VOIP lost it's DHCP server. the phone is back up now but the properties of the card was configured for 100mb which made the connection really slow.
