Managing the Internet connectivity of multiple Windows computers in a local network is a frequent administrative necessity, often driven by security requirements, mandatory maintenance periods, or simply controlling user access in scenarios such as during the conduction of examinations. Manually performing this task on dozens of machines—logging into each, navigating to network settings, and disabling/re-enabling components—is not only time-consuming and tedious but is highly susceptible to human error. Such manual efforts reduce IT efficiency and increase the risk of inconsistent network state across the organization.

To overcome these concerns, a script-based solution offers unparalleled utility. By leveraging the built-in capabilities of PowerShell, administrators can transform a manual, hour-long chore into an automated batch process. PowerShell is exceptionally effective for this task because its cmdlets (like Invoke-Command and network management tools) allow for secure, remote execution of commands across the entire domain, all while reading instructions from a centralized source like an Excel file. This automation ensures consistency, provides auditable logging of every successful or failed operation, and allows the administrator to quickly and effectively manage internet access without disrupting local network operations.

This set of scripts allows an administrator to remotely enable or disable network connectivity on multiple Windows computers by reading instructions from an Excel file.
