Microsoft has acknowledged that recent security updates for Windows 11 are causing networking complications for enterprise users utilizing the Windows Subsystem for Linux (WSL), particularly affecting those who installed the KB5067036 update from October 28, 2025, or subsequent updates like KB5072033. Users are experiencing difficulties with certain third-party VPN applications when the mirrored mode networking feature is enabled, leading to "No route to host" errors within WSL environments. This issue primarily impacts OpenVPN and Cisco Secure Client. The root cause is the failure of VPN applications' virtual network interfaces to respond to Address Resolution Protocol (ARP) requests. Home users on Windows Home or Pro editions are unlikely to be affected. Microsoft is investigating the issue but has not provided a timeline for a resolution or workarounds. WSL, launched in March 2018, allows users to run Linux distributions natively on Windows, with WSL 2 introduced in May 2019 featuring a real Linux kernel. Microsoft open-sourced WSL at Microsoft Build 2025, making its source code available on GitHub, except for some components that remain part of Windows.

NordVPN features an innovative Threat Protection Pro that scans downloaded files for threats, assesses applications for vulnerabilities, blocks malicious websites, and reduces intrusive ads and trackers. It is the first VPN to receive AV-Comparatives’ anti-phishing certification, but it lacks full antivirus capabilities like system scans and malware removal. The feature is included in the Plus, Complete, and Prime subscription tiers for Windows and Mac users, with specific pricing structures for each tier. NordVPN is noted for its speed, extensive server network in 126 countries, and strong privacy features. Norton Secure VPN, while user-friendly, has issues such as IPv6 leaks, excessive data collection, and concerns related to its US jurisdiction. It has slower speeds, a limited server network, and lacks Linux support. Norton is working on improvements, including support for various streaming devices, but alternatives may provide better privacy features and performance.

The Readiness team analyzes updates monthly, providing testing guidance based on Microsoft patches. The November release includes updates for network infrastructure, remote connectivity, and wireless components, requiring careful testing despite no high-risk flags. Key areas for testing remote connections include validating packet transmission over IPv4 and IPv6, transferring large files over IPv6, testing web browsing and workflows with Microsoft Teams and Skype, and verifying Remote Desktop connections. The updates significantly impact application communication capabilities, necessitating dedicated validation for IPv6 alongside IPv4 operations.

Administrators use the Dynamic Host Configuration Protocol (DHCP) service to manage IP address configurations for clients efficiently. Deploying multiple DHCP scopes on a single server is more practical than having separate servers for each subnet. DHCP operates through a four-step lease process: discover, offer, request, and acknowledge. To install a DHCP server, the PowerShell cmdlet Install-WindowsFeature DHCP -IncludeManagementTools is used, and the server must be authorized in Active Directory. A single DHCP server can manage multiple scopes, each with specific configurations for different subnets, such as DevNet, ProdNet, SalesNet, and EngineersNet. Each scope can have unique IP address ranges and settings, and additional scopes can be created by adding network interface cards (NICs) to the server. Server options apply globally, while scope options are specific to individual scopes. Reserved IP addresses can also be configured within each scope.

Your Internet Service Provider (ISP) provides internet access and DNS addresses, which are essential for navigating the web. However, relying solely on your ISP's DNS servers can lead to privacy issues, slower speeds, and unreliability. Third-party DNS services can enhance the internet experience on Windows 10. The Domain Name System (DNS) translates website names into IP addresses, and any disruptions can hinder browsing. Changing DNS settings can improve internet speed and safety, with options for parental controls. To change DNS settings on Windows 10, users should access Advanced Network Settings, select the connection to modify, choose IP Version 4 (TCP/IP v4), and enter the preferred and alternate DNS server addresses. iTop VPN is a service that protects online activities, encrypts traffic, alters IP addresses, and safeguards DNS settings. It offers a fast and free service, DNS protection from unauthorized changes, privacy security features, and the ability to unblock content.

Macs are facing an increasing number of cybersecurity threats, with malware targeting macOS rising from eight families in 2021 to 21 in 2023. To protect against these threats, users are advised to implement antivirus software, maintain regular backups using tools like Apple's Time Machine and cloud services, enable the built-in firewall, use password managers for secure password storage, and utilize a VPN for secure internet connections, especially on public Wi-Fi.
