The Dynamic Host Configuration Protocol (DHCP) server is a network protocol that automatically assigns IP addresses. It also distributes the network configuration to all connected devices, such as the DNS server, subnet mask, and default gateway. But often, an error can appear when renewing, releasing, or leasing an IP address. If you receive unable to contact your DHCP server error on Windows 10, try these fixes.

Fix Unable to Contact Your DHCP Server Error on Windows 10

A DHCP server allows for network configuration of newly connected devices without setting up static individual IP addresses. Instead, the process is automated with the DHCP server and network interface controller often communicating to refresh and release the addresses.

Unfortunately, a lack of communication between the protocols can interrupt internet access. If you can no longer surf the internet due to the inability to contact your DHCP server error, here are some solutions.

1. Register Your DNS

At times, initiating a manual dynamic registration for the DNS name and IP address can fix the error. You can do this by registering your DNS using a command prompt.

Step 1: Type cmd on the Windows search bar, and the right-hand side, select Run as administrator.

Step 2: Type this command and press Enter

ipconfig /registerdns

Command prompt ipconfig registerdns

Step 3: Restart your computer and confirm if the error is resolved. If not, try the other fixes.

2. Restart Your DHCP Server

The error can occur if the DHCP has stopped or your system can’t connect to the service. To resolve this, restart your DHCP client service.

Step 1: Press Windows + R keys, type services.msc in the run dialog box and press Enter.
