I have an issue with NLB using this ethernet card. Im not using Virtual but Physical blade server. when i try to create NLB using windows Load Balancing over Unicast Mode, IP on this Ethernet Card suddenly disappear. i'm try to check over command prompt using "ipconfig" command, the information about IP address, Mac address and the other also disappear. I try to update the driver into the latest one, but got no luck.
does anyone here know what should i do with this case ? operating system is using Windows Server 2008 R2 SP1
