My NIC Adapter on my Latitude D600 is working fine its a 'Broadcom 570x Gigabit Integrated Controller'. I'm running WinXP SP2. I successfully join our company domain, login with my network account and surf the Internet afterwards. But the issue is that it's prompting me that it's 'Found New Hardware'...the 'Network Controller'. But I've already installed the NIC Adapter and the modem drivers. If I ignore & cancel out of the message, I don't experience any problems with my laptop whatsoever. What 'Network Controller' driver is the OS asking for, though? Thanks in advance for your reply and assistance!
