Windows 7, TCP/IP Network Interface Configuration, Event ID 4199

    Question

  • I have been receiving an Error window for a few weeks now that has the above Identifier and then states "Another computer on this network has the same IP address as this computer.  Check Windows System Events Log."  I have checked the log and found the event details and the Resolve is - "Assign a different static IP address".  When I go to the Network Sharing Center and check the properties for IPV4 and IPV6 they are both set to assign IPs.  Also when I go to dos ipconfig/all, I find both IPV4 and IPV6 are marked preferred.  I run 2 computers (1 laptop (getting error) & 1 desktop - both Windows 7) and a printer on this work network which is wired and wireless (WPA).  I also have this laptop computer assigned to connect to my home network with another computer.  Any suggestions?

  • Hi awabel,

     

    Thanks for post here.

     

    The system prompt indicate that another computer or device which in the same network may being assigned an IP address that as same as your laptop assigned. So it caused IP address conflict.

     

    Have you deployed DHCP service in your network?

    If yes, please check the article below to solve this issue:

    If not, I suggest to check the event log of your laptop, the MAC address of the problematic computer will be recorded in the event description , if you are using “Smart” network switch device, then login the device  and check the MAC address table to located the switch port of computer or device connected . If you are using a normal network switch, then I’m afraid you have to check the IP setting of computers and devices in your network one by one.

     

    Thanks.

    Assign a different static IP address

    If your IP address is statically assigned and does not originate from a DHCP server, change the IP address assigned to the network interface so that it does not duplicate another IP address on the network.

    To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

    To change the static IP address:.Click Control Panel, doubl-click Network and Sharing Center, and then click Manage network connections.Right-click the network interface you want to update, and then click Properties.Click Internet Protocol Version 4 (IPv4), click Properties, and then type a different IP address Address.

    Verify.  To verify that an IP address is assigned:  At the DHCP-enabled client computer, click Start, click Run, and then type cmd.Type ipconfig /all to view lease-status information.The output of the ipconfig command should show an IPv4 or IPv6 address marked "preferred
