Server 2008 R2 NIC not holding Static IP


  • Hello

    I have a Dell 2950, Server 2008 R2 SP-1, it is a DC, DHCP, DNS, WINS, Etc

    Local Area Connection 1 is the only active NIC with:




    IPV6 Disabled

    Local Area Connection 2 is disabled

    I had DHCP, DNS, Etc all working fine, the server was down for 2 weeks for a move, it is a DC and the only server (I know, I know, not a good idea)

    When I fired it back up, the static was gone the the NIC defaulted to DHCP

    What would cause this?  I called Dell about anything configured for this, they said there is none,

    Also noticed if I add DG as same (Only 1 server is DC, WINS, DNS, DHCP, the DG returns to empty

  • Hi B.

    Based on your description, please make sure that this is not changed by someone else with admin access to the domain controller. Besides, we can check DHCP logs under Applications and Services Logs\Microsoft\Windows\Dhcp-Client in Event Viewer to see if some related logs were logged.

    Moreover, for this question is not related to group policy and more related to network, in order to get better help and analysis, it's recommended that we ask for suggestions in the following forum.

    Best regards,
