I'm having issues with a Windows Server 2012 - Dell PowerEdge R300.

Every time the server restarts the network adapter gets limited connection and does not work. I have to locally disable the network adapter and re-enable and it works normally until the next reboot.

Network Adapter: Broadcom NetXtreme Gigabit Ethernet Driver version: 16.6.0.4 - specifically from Broadcom Website since Dell Support is with 16.2.0 and the issue still happening.

After the issue I look into the Event viewer however does not show me anything useful.

Any ideas what could be causing it ?

    `1.` Have you checked for a firmware update for the NIC? `2.` What other diagnostics/troubleshooting have you performed? `3.` Have you verified DNS settings and the default gateway settings? `4.` Can you manually run these tests successfully? - http://blogs.technet.com/b/networking/archive/2012/12/20/the-network-connection-status-icon.aspx – joeqwerty Feb 24 '15 at 21:28
  • Are you statically assigning an IP Address? Typically you do not use dynamic addressing for servers. – Jon Moody Feb 24 '15 at 23:21
  • I ran into this same issue at my last job with a PowerEdge... I've completely forgotten the fix. I'm so sorry. I'm thinking it was something dumb like disable IPv6 (if you don't need it), but am not sure. You could start there. – armani Mar 03 '15 at 20:33

I've seen this problem with Dell servers. Go into the system (hardware) setup and look for a conflicting network adapter assignment such as Static with a useless default IP address. If you wish to continue assigning a dynamic IP address to that NIC, make sure the BIOS is configured for the same at boot-up.
