This article explains how to create a Windows shell extension (a small DLL) that adds an "Open Internet" shortcut to EVE-NG nodes or local VM consoles so you can quickly open a web browser pointing to the node's management IP or a proxy URL. It covers goals, design choices, prerequisites, step-by-step implementation in C++ using the Windows Shell API, security considerations, deployment, and troubleshooting.
When Windows sees these custom headers, it sometimes freaks out. It defaults to the generic "Open Internet Shortcut" dialog. The "DLL" you see referenced is usually the system trying to hand off the URL to url.dll or a similar system library to execute the protocol, but because EVE-NG is running on a local loopback or a custom port, Windows treats it as an unknown file type. eve-ng open internet shortcut extension dll
If you are using Firefox, it may ask what application to use for a "telnet" link. You must manually select PuTTY (usually located in C:\Program Files\EVE-NG\putty.exe) and check the box to "Always use this application". Article: Creating an "Open Internet" Shortcut for EVE-NG
Here is the definitive guide to eliminating the DLL error and restoring seamless link opening from your EVE-NG lab. It defaults to the generic "Open Internet Shortcut" dialog

Registry Files: Automatically maps telnet://, vnc://, and ssh:// protocols to the correct local apps.
The "Open Internet Shortcut Extension DLL" message in EVE-NG typically appears when the Windows operating system is unsure how to handle a telnet://, ssh://, or vnc:// link clicked within a web browser. This occurs because EVE-NG uses these custom URL schemes to trigger local terminal clients (like PuTTY or SecureCRT) to open nodes. Why This Happens
