LanSend by LizardSystems is a specialized administrative utility designed to bulk-broadcast instant desktop notifications, alerts, and emergency messages to multiple network computers simultaneously. It functions as a modern alternative to the deprecated Windows net send or msg command line utilities.
Because LanSend acts as a transmitter tool directly to Windows machines, deploying it across large enterprise networks requires careful directory integration, network port configuration, and security handling. Step 1: System Requirements & Network Provisioning
Before running the utility, network administrators must verify that the environment can support the message broadcasts.
OS Support: Ensure management consoles and target devices run supported operating systems (LanSend includes full Windows 11 and Windows 10 support).
Firewall Adjustments: Open required SMB/RPC ports (Port 445 and Port 139) on internal enterprise firewalls.
Service Configurations: The Windows Remote Registry service and RPC (Remote Procedure Call) locator services must be enabled and running on all target workstations to listen for incoming messages. Step 2: Installation and Elevated Privileges
Unlike typical client-server chat applications, LanSend is a lightweight administrator tool. It only needs to be installed on the operator’s console rather than every target machine.

Run the installer using an account with Domain Administrator privileges, as standard user accounts do not have permission to push registry or messaging hooks to remote workstations.
Step 3: Populate Target Computers and Active Directory Integration
To manage an enterprise scale network, typing individual names is inefficient. LanSend allows you to build out the “Add Computers Wizard” infrastructure:
Active Directory Sync: Link LanSend directly to your local domain controller to pull computers automatically via Organizational Units (OUs).
Network Scanning: Use the built-in improved network scanning engine to sweep specific IP subnets and pull active hosts.
File Import: Import an external text or CSV file populated with enterprise hostname lists.
Security Note: Ensure your software is updated past version 3.2, as older legacy versions contained an import buffer overflow vulnerability (patched in modern updates). Step 4: Structuring Recipient Groups
To prevent alert fatigue, organize your network using the Computer Lists feature:
Departmental Groups: Build distinct target categories for Finance, IT, Human Resources, or Operations.
Geographic/Floor Groups: Group targets by physical server rooms, building floors, or remote branch offices. Step 5: Customizing Notification Templates
For consistent enterprise communication, define message templates and priority types beforehand:
Emergency/Urgent Alerts: Formatted with high-visibility flags for immediate building evacuations, critical cyber security threats, or sudden server outages.
Informational Notices: Lower-priority notices for scheduled weekend patches, printer maintenance, or pending system reboots.
Macro Tokens: Embed automated variables such as %USERNAME% or %COMPUTERNAME% so that mass-sent messages auto-populate user-specific details on their desktop screens. Step 6: Deploying and Scheduling Messages
Once configured, you are ready to transmit messages via the console dashboard: Select your target group from the left pane panel. Draft the text body or select an existing template.
Choose either Instant Delivery or use the Scheduled Messaging Engine to queue alerts for specific maintenance windows.
Monitor the Message History log to audit which machines successfully acknowledged and displayed the notification.
If you’d like to narrow down your network deployment strategy, let me know:
What operating systems are running on the majority of your target workstations?
Are you planning to pull your computer lists using Active Directory or manual IP scanning?
Do you need assistance mapping out specific firewall rules for network wide notifications? PowerShell Script To Send Message To Network Computer(s)
