How to Fix DHCP Server Keeps Stopping Error on Windows 11: Complete Troubleshooting Steps

Experiencing the DHCP Server keeps stopping error on Windows 11 can disrupt your network connectivity. This issue prevents your computer from assigning IP addresses properly, causing internet and local network problems. Fortunately, there are straightforward steps you can follow to troubleshoot and fix this problem.

This guide will walk you through simple to advanced methods to resolve the DHCP Server error effectively. Each step is explained clearly, so even beginners can follow along without hassle.

Before diving into troubleshooting, it’s important to understand what DHCP does. DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses to devices on your network, allowing them to communicate smoothly. If the DHCP Server service stops unexpectedly, your device may fail to get a valid IP address.

Let’s get started with some quick checks to ensure your system is ready for troubleshooting.

Quick Note: Prerequisites and Initial Checks

  • Check your Windows updates: Make sure your system is fully updated. Sometimes, outdated system files cause service issues.
  • Run as Administrator: For many troubleshooting steps, you’ll need to run commands or access settings with administrator rights.
  • Network Connection: Verify your network adapter is enabled and properly connected to your router or modem.
  • Backup important data: Though unlikely, some troubleshooting steps may affect network settings—backing up ensures you can restore settings if needed.

Step 1: Restart the DHCP Server Service

Sometimes, the DHCP Server service might stop temporarily due to a minor glitch. Restarting it can solve the problem quickly.

  1. Press Win + R to open the Run dialog box.
  2. Type services.msc and press Enter to open the Services window.
  3. Scroll down and find DHCP Server from the list.
  4. Right-click on DHCP Server and select Restart.
  5. If the service is not running, right-click and choose Start.

Why this matters: Restarting the service resets its state, which can resolve temporary errors or conflicts preventing it from running.

Step 2: Check the DHCP Server Service Startup Type

The DHCP Server service might be set to manual or disabled, which causes it to stop running automatically. Setting it to automatic ensures it starts whenever Windows boots.

  1. Open the services.msc window again.
  2. Right-click on DHCP Server and select Properties.
  3. In the General tab, find Startup type.
  4. Set it to Automatic from the dropdown menu.
  5. Click Apply and then OK.
  6. Restart your computer to confirm the change.

Why this matters: If the service does not start automatically, your network devices won’t receive IP addresses after rebooting, causing connectivity issues.

Step 3: Run Network Troubleshooter

Windows 11 has a built-in troubleshooter that can detect and fix common network-related problems automatically.

  1. Go to Settings by pressing Win + I.
  2. Navigate to System > Troubleshoot > Other troubleshooters.
  3. Find Network Adapter and click Run.
  4. Follow the on-screen instructions to complete the troubleshooting process.

Why this matters: The troubleshooter can detect misconfigurations or issues that might cause the DHCP Server to stop, and it applies fixes automatically.

Step 4: Reset TCP/IP Stack

Sometimes, corrupted network settings can cause DHCP service errors. Resetting the TCP/IP stack restores network configurations to their default state.

  1. Open Command Prompt as Administrator:
    – Press Win + X and select Windows Terminal (Admin) or Command Prompt (Admin).
  2. Type the following commands one by one, pressing Enter after each:
netsh int ip reset
netsh winsock reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

Restart your computer after running these commands.

Why this matters: These commands reset key network components and clear stale DNS caches, which can fix DHCP-related issues caused by corrupted settings.

Step 5: Check for Conflicting Software

Antivirus programs or third-party firewall software can interfere with the DHCP Server service. Temporarily disabling these programs can help identify if they are the cause.

  1. Temporarily disable your antivirus and firewall software.
  2. Restart your computer and check if the DHCP Server service stays running.
  3. If the service works, configure your security software to allow DHCP traffic or consider switching software.

Why this matters: Security software sometimes blocks essential network services, mistaking them for threats.

Step 6: Perform a System File Check (SFC)

Corrupted system files can cause services like DHCP Server to malfunction. The System File Checker scans and repairs these files.

  1. Open Command Prompt as Administrator.
  2. Type the following command and press Enter:
sfc /scannow

Wait for the scan to complete. If any issues are found, Windows will repair them automatically.

Restart your PC and verify if the DHCP Server issue is resolved.

Alternative Method: Use Windows PowerShell to Restart DHCP Server

If you prefer using PowerShell, you can restart the DHCP Server service with a simple command.

  1. Open Windows PowerShell as Administrator.
  2. Type the following command and press Enter:
Restart-Service -Name "DHCPServer"

This command stops and starts the DHCP Server service efficiently.

FAQs

Why does the DHCP Server keep stopping on Windows 11?

This can happen due to corrupted network settings, conflicting software, disabled service startup type, outdated drivers, or system file corruption.

Can I fix this issue by updating my network adapter drivers?

Yes, outdated or faulty drivers can cause network service interruptions. Updating your drivers from the Device Manager might help.

Is it safe to reset the TCP/IP stack?

Yes, resetting TCP/IP stack restores network configurations to defaults without deleting personal data. It often resolves network connectivity issues.

What if the DHCP Server service is missing in the Services list?

This might indicate a deeper system issue. Running System File Checker or performing a repair install of Windows could be necessary.

Do I need to configure anything after resetting network settings?

Usually, no. Windows automatically configures network settings after resets, but if you use static IP addresses, you may need to reconfigure them.

When Nothing Works

If you have tried all the above steps and the DHCP Server keeps stopping, consider the following final steps:

  • Check Event Viewer: Look for detailed error messages related to the DHCP Server service to identify specific issues.
  • Perform a System Restore: Restore your system to a previous point when DHCP was working correctly.
  • Contact Microsoft Support: Use official Microsoft support channels for advanced help.
  • Reinstall Windows: As a last resort, a clean installation can fix persistent system-level errors.

Conclusion

The DHCP Server keeps stopping error on Windows 11 can be frustrating but is usually fixable with some simple troubleshooting. Starting with restarting the service and verifying startup settings often solves the problem.

Running built-in troubleshooters, resetting network components, and checking for software conflicts further helps resolve the issue. If problems persist, system file repairs or professional support may be necessary.

By following these detailed steps, you can restore your network’s smooth operation and enjoy uninterrupted connectivity on your Windows 11 device.
