Mass Change VNC Passwords

Bozteck VENM Remote Desktop Manager allows you to mass change VNC passwords or Windows authentication settings on remote computers over the network.  This article will walk you through changing the VNC authentication on a remote computer on the LAN running UltraVNC with Windows Authentication enabled.  The process is very similar if you are setting the password for a computer that is using the standard VNC password authentication.

To make use of this feature, you must first download and install Bozteck VENM Remote Desktop Manager.  Once installed, follow this guide to get the initial setup completed.

Step 1 – Right-click one or more computers and choose the menu item below


Step 2 – Enter a user account that is Admin on the remote Computer(s)


Step 3 – Choose the authentication desired for the computer(s)

You should now be able to connect to the remote computer(s) using the updated VNC authentication settings.

The following must be true for this all to work:

  • You must have either a registered or trial version of Bozteck VENM installed on your PC
  • You should have a service account configured in VENM with admin access on the PC’s
  • Windows file sharing ports should not be blocked by a firewall
