On reboot My Dell Sever does not retain its static IP address and subnet mask.  Even if I re-ip the unit and go back into the IP connection it does not have the IP address or subnet mask.

I have tried the following:  
1. Win update
2. nic drivers.
3. Cleared arp cache

Its a dell, r410 -
New nic driver version is 6.2.90

are you saying that you are setting a static address, and on reboot it is changing to a DHCP address?, or that the static address is changing?

Hi thank you for the post. It's a static address and on reboot the ip and subnet mask are blank . Gateway and dns doesn't disappear.

from an elevated command prompt can you run the below

netsh int ip reset c:\resetlog.txt

Open in new window


and then post the resetlog.txt as an attachment

You are using latest driver but obviously you did not install latest firmware for your NICs. For R410 please download and install (6.4.4)

Are you using HyperV on this machine? If yes probably you looking to wrong NIC as HyperV adding a virtual network when OS manage the system. Let me know how it goes.
