Thank you for the response. I am developing an application that connects to a VM using Apache Guacamole embedded in an iframe. However, I would prefer not to use an iframe. Is there an alternative or recommended way to establish the VM connection without using an iframe? ________________________________ From: Nick Couchman <[email protected]> Sent: 05 February 2026 22:11 To: [email protected] <[email protected]> Subject: Re: Guacamole VNC Connection Asking for Windows Login on First Connection

If you're connecting with VNC, then you're not entering the Windows username and password in the connection settings, you're entering the VNC username and password. Depending on what VNC server you're connecting to, the VNC credentials may be the same as the Windows credentials, but you're authenticating to VNC, not to Windows. If the Windows system is not already logged in under a specific user account, you may get the Windows login dialog after you've already connected with VNC. Again, this will depend on the VNC server you're using as to whether it has the hooks to be able to log in to Windows. This isn't really a Guacamole issue, this is just the nature of VNC - most VNC packages do not contain the same capability that RDP, for example, has, where the network authentication also functions to login to the O/S. The only way to resolve this is to find a VNC server that has this functionality, if such a package exists. -Nick
