Fixing DHCP Lease Release Issues on Windows Server

Key Notes

  • Check for and install any pending server updates.
  • Manually change the server’s IP address using PowerShell commands.
  • Restart the DHCP Client Service to reset network configurations.

Tackling DHCP Lease Release Errors in Windows Server Core Edition

When setting a static IP address in Windows Server Core Edition, encountering a ‘Failed to Release DHCP Lease’ error is a common issue. This guide addresses various workarounds to solve this problem effectively.

Resolving the Issue of Windows Server Failing to Release DHCP Lease

If your Windows Server struggles to release a DHCP Lease, try the following solutions:

  1. Step 1: Ensure Server Updates Are Installed
  2. Step 2: Force a Change of the IP Address
  3. Step 3: Restart the DHCP Client Service

Step 1: Ensure Server Updates Are Installed

Bugs in your operating system can cause network setting modifications to fail. Check for updates by navigating to Settings, selecting Update & Security, and clicking Check for updates. Install any available updates, restart your server, and verify if the issue persists.

Step 2: Force a Change of the IP Address

If no updates are available and the issue remains, manually change the server’s IP address using the command line interface. Access PowerShell as an administrator and run Get-NetAdapter to view your network interfaces. Identify the adapter you want to modify.

To remove the existing IP address, execute:

Remove-NetIPAddress -InterfaceAlias [YourInterfaceAlias] -confirm:$False

Replace [YourInterfaceAlias] with your adapter’s interface alias. For instance, if your alias is Ethernet0, the command will look like:

Remove-NetIPAddress -InterfaceAlias Ethernet0 -confirm:$False

Now, to assign a new IP address, run:

New-NetIPAddress -InterfaceAlias {NAME} -IPAddress {IP} -PrefixLength {L} -DefaultGateway {GATEWAY_IP}

Here’s what each parameter represents:

  • InterfaceAlias {NAME}: Replace with your actual interface alias.
  • IPAddress {IP}: Input the new desired IP address.
  • PrefixLength {L}: Provide the subnet mask prefix length.
  • DefaultGateway {GATEWAY_IP}: Enter your network’s gateway IP address.

After replacing the placeholders, your final command might read:

New-NetIPAddress -InterfaceAlias Ethernet0 -IPAddress 192.168.1.4 -PrefixLength 24 -DefaultGateway 192.168.1.1

Step 3: Restart the DHCP Client Service

The DHCP Client Service manages IP address allocation. To restart it, open PowerShell and execute:

Restart-Service DhcpClient

Check if this resolves the issue. If the error persists, you can also try resetting the Winsock protocol with:

netsh winsock reset

Additional Tips

  • Always ensure your network drivers are updated to avoid compatibility issues.
  • Consistently verify that there are no duplicate IP addresses in your network.
  • Regularly monitor DHCP settings to promptly identify and correct configuration problems.

Summary

This guide provided strategies for resolving the frequently encountered ‘Failed to Release DHCP Lease’ error in Windows Server Core Edition. By verifying updates, forcing an IP change, and restarting critical services, users can effectively manage their network configurations.

Conclusion

Resolving DHCP lease release issues in Windows Server Core Edition is essential for maintaining network stability. Implement the outlined methods for effective troubleshooting and optimize your server’s network management.
