Ah.. I forgot..

I cannot ping any device from server but I can ping 127.0.0.1 so TCP/IP protocol and drivers seem to be fine.. I think...

Hi Dms

Known issue? I know hot to TS it however I do not have any customer advisory or so for it? Do you have any?

Thanks in advance

BTW this procedure is use without the need of disabling anything, no TOE or RSS so the NIC will have all functions available.

When you try to update the driver it will not overwrite the existing one, so, what we do is actually delete the driver from windows registry and we installed manually. This way it will work

Solution.
Download the driver for your OS version on a USB Key, save the driver into a temporary folder in the affected server, make sure that the folder and its contents are not marked as read only.
1) Go to the device manager and right click on the NIC device and select Uninstall
2) Go to Start > Programs > Accesories > System Tools > System Information.
3) On the left side click on the + sign to expand the menu > Click on the + sign to expand Network menu > click on adapter.
4) On the right page look for the HP NC31xx Fast Ethernet NIC Driver location. Copy the driver location and then go to the folder where the driver resides and manually delete it.
5) Reboot the server and stop windows driver installation. If it prompts for you to choose the new driver cancel all request and get into windows, once there install the driver from the .exe file that you downloaded.
6) Reboot the server. By now you should be able to use the NIC card.

You may want to read this long thread. I'm working on this issue with support as well. Even the latest drivers aren't 100%
