Windows 10: Failed to obtain IP address from DHCP Server

​

DHCP stands for Dynamic Host Configuration Protocol. It provides IP addresses and other related configuration information such as subnet mask and default gateway to the client machine.

The DHCP Server service terminated without a valid clue

Hi Chhetri Suman,

Thank you for writing to Microsoft Community Forums.

DHCP (Dynamic Host Configuration Protocol): Every device on TCP/IP needs unique IP address to access the network. DHCP controls the allotment of IP addresses. However, if
you can access internet, DHCP should work fine. But if there is some issue with the internet, you can follow these steps and resolve the DHCP error.

I suggest you to follow the troubleshooting steps mentioned below:

1. Press Windows and
   R key together on your Keyboard.
   
2. Type Control and hit enter.
   
3. Click on Network and internet > click on Change adapter settings
   on the left pane.
   

4. Right click on the Ethernet connection you are using and select properties.


5. Select Internet protocol version 4 (TCP/IPV4) and click on properties.


6. Check the following radio boxes:

• Obtain an IP address automatically
• Obtain DNS server address automatically

7. Now windows 10 will retrieve the IP address automatically.

Hope it helps.

DHCP renewal of IP address with ISP denied

Hello

I wonder if anyone can advise concerning a series of messages appearing in the logs of my two networked computers?

Examples of the messages:

• ON ALPHA: The IP address lease 192.168.0.3 for the Network Card with network address 0x0024E8F1F44F has been denied by the DHCP server 192.168.0.1 (The DHCP Server sent a DHCPNACK message).
• On BETA: The IP address lease 192.168.0.2 for the Network Card with network address 0x7071BCA36DBF has been denied by the DHCP server 192.168.0.1 (The DHCP Server sent a DHCPNACK message).

The advent of either appears to kill my internet connection requiring a router restart. I should add that sometimes both PCs are on, but often only one is. In the latter case, the issue still occurs on the active PC, normally BETA because it is the more powerful of the two.

To describe this network, ALPHA is a Windows 7 32bit laptop, and BETA is a 64bit Windows 10 desktop. Both PCs are connected to the internet via a Netgear DC834GV3 router connected to my ISP.

ALPHA has LAN network address 192.168.0.3, and BETA is 192.168.0.2. The router is 192.168.0.1. A simple network map is displayed below:






Both PCs are getting on a bit but are still fully working. The PCs and router are powered off usually and the cables disconnected from the mains, but the messages still occur with the router left on but the PCs switched off.

Thanks
