Getting Started with Ultravnc Installation
When you're looking to get Ultravnc onto an end-user's computer, you know, the first thing that often comes to mind is how to make the installation as smooth as possible. Nobody really wants to manually set up a password on every single machine. So, people often wonder, "Is there any command line option to include remote acess password while install ultravnc?" This question comes up quite a bit, actually, especially when deploying to many PCs. It's about making things easier, right?
Automating Password Setup During Installation
Automating the password setup is, well, pretty much a must for large deployments. If you're like many people, you're trying to set the password for a Ultravnc server without having to use the system tray menu. This is because you want to automate installation, and that's a very sensible goal. Some folks have tried using `uvnc_settings.exe` for this, which is a good idea. The goal is to create a script to install only the VNC server, register it as a service, and then set your password. This can save you a lot of time, honestly, instead of needing to set up a password one by one.
Installing Only the Ultravnc Server and Registering It as a Service
To get the most out of Ultravnc, especially for unattended access, installing just the server and registering it as a service is a pretty common approach. This helps, for example, with allowing UAC screens input from VNC sessions. When you install Ultravnc server and then register it as a service, everything usually works fine. This way, the VNC server starts automatically with the system, even before anyone logs in, which is very handy for remote maintenance. People often have many VNC installations, and they all have the same configuration, so automating this part is truly helpful.
Configuring Ultravnc for Optimal Performance
Once Ultravnc is installed, getting it configured just right can make a real difference in how well it works for you. There are a few key settings and practices that can help ensure your remote connections are stable and secure. It's about getting the details sorted, you know, so the experience is as smooth as possible for both you and the end-user. Sometimes, a small tweak can clear up a big headache, which is pretty much always a good thing.
Ensuring Viewer and Server Compatibility
A really important thing to keep in mind is that the Ultravnc viewer needs to be Ultravnc, and it's best to use the same version as the Ultravnc server. This is to be sure they speak the same protocol. If you're running into strange connection issues, or maybe things just aren't quite right, checking your versions is a good first step. For instance, many people use version 1.3.2a for both server and viewer in a direct connection, and that works great for them. Mismatched versions can, in some cases, cause unexpected behavior, so keeping them aligned is a sensible choice.
Using MS Logon for Windows Authentication
For better security and easier management within a Windows environment, using MS Logon for authentication is a very popular option. We are using Ultravnc version 1.3.4.2 and have the configuration setup to use MS Logon for Windows authentication. We set this up, and it works great. This means users can connect using their existing Windows credentials, which simplifies things quite a bit, especially in business settings. It's a way to integrate Ultravnc more seamlessly with your existing network security policies, offering a more professional approach, in a way.
Saving Passwords for Quicker Connections
For those who connect to the same servers often, having to type in a password every single time can get a little tiresome, you know? So, a common question is, "Is there a way to save the password with the latest version so you do not get prompted when connecting to a server?" While this offers convenience, it's something to think about carefully from a security standpoint. For personal use or trusted networks, it can speed things up a lot. For other situations, you might want to stick with entering the password each time, just to be on the safe side, actually.
Troubleshooting Common Ultravnc Issues
Even with the best setup, sometimes things just don't go as planned. Ultravnc, like any software, can have its quirks. Knowing how to quickly diagnose and fix common problems can save you a lot of time and frustration. We've all been there, staring at a screen wondering why something isn't working. So, let's look at some of the more frequent issues people encounter and how to get past them, because, you know, getting back to work is the main goal.
Dealing with the Black Screen Problem
One of the more frustrating issues people report is seeing just a black screen when connecting with VNCViewer. For example, on a Windows 2019 server, someone installed Ultravnc 1.4.3.6, but when they connected using VNCViewer, they could see just a black screen. This can be caused by a few things, like display driver issues on the remote machine, or maybe a problem with the VNC server not properly capturing the display. Sometimes, simply restarting the Ultravnc service can help, or making sure the display settings on the remote server are not too unusual. It's a common enough problem that it's worth knowing a few tricks for it, really.
Addressing UAC Screens and Input from VNC Sessions
User Account Control (UAC) prompts in Windows can sometimes be a hurdle for remote access tools. When you're trying to interact with a UAC screen via VNC, it can appear as if your mouse and keyboard input aren't working. This is often why people install Ultravnc server and register it as a service, specifically to allow UAC screens input from VNC sessions. When registered as a service, Ultravnc runs at a higher privilege level, which generally helps it interact with those UAC prompts more effectively. It's a pretty essential step for full remote control, you know, especially in modern Windows environments.
Managing schook.dll Processes
Occasionally, you might run into issues with `schook.dll` or `schook64.dll`, which are components Ultravnc uses for certain functions. These DLLs are actually very often injected into `explorer.exe`. If you're having trouble, you can use `taskkill` to kill all processes which use `schook.dll`/`schook64.dll`. This can sometimes resolve conflicts or free up resources if the DLLs are causing instability. It's a bit of a deeper troubleshooting step, but it can be really effective if you suspect these components are causing problems, as a matter of fact.
Advanced Features and Considerations
Beyond the basic connect-and-control, Ultravnc offers some capabilities that can make it even more useful, while also having some limitations that are good to know about. Thinking about these advanced features and considerations can help you decide if Ultravnc is the right tool for all your specific needs. It’s about understanding the full scope of what it can do, and where you might need to look for other solutions, which is pretty important for planning, right?
Remote Desktop Audio Support
One feature that many people ask about is remote desktop audio or sound. "Is it possible to add support for hearing the remote desktop audio/sound?" is a common question. Honestly, audio over VNC seems to be a pretty rare thing, and it often requires a separate solution. If not, people ask, "is there another way to enable remote desktop sound/audio and use Ultravnc sep?" Typically, VNC protocols are designed for visual display and input, not audio. So, if sound is a critical part of your remote access, you might need to look into other remote desktop software or dedicated audio streaming solutions that work alongside Ultravnc. It's just one of those things that Ultravnc wasn't primarily built for, you know.
Public Key Storage and Management
For enhanced security, especially when dealing with sensitive connections, public key authentication can be a good option. Some users have been test deploying the newest version of UVNC on machines that have older working versions on them with public keys stored in the `uvnc bvba\ultravnc` folder. This suggests that Ultravnc can use public keys for authentication, adding an extra layer of security beyond just passwords. Managing these keys correctly is important, as they play a role in verifying the identity of the connecting parties. It’s a slightly more involved setup, but it definitely boosts security, which is pretty much always a good thing.
Scripting Ultravnc Uninstallation
Just as important as installing software is being able to remove it cleanly when it's no longer needed. Someone mentioned, "Well, I did write a script to uninstall Ultravnc pretty reliably." This highlights the value of having a robust uninstallation process, especially for IT environments where software needs to be managed efficiently. A good uninstallation script can ensure that all components are removed, preventing leftover files or registry entries that might cause issues later. It's part of the full lifecycle management of any software, and Ultravnc is no different, really.
Frequently Asked Questions About Ultravnc

Can I automate the password setup when installing Ultravnc?
Yes, you can, actually. Many users want to automate this process to avoid manually setting passwords on each machine. You can typically use command-line options or tools like `uvnc_settings.exe` within a script to pre-configure the remote access password during installation.

Why do I sometimes see a black screen when connecting to an Ultravnc server?
A black screen is a fairly common issue, and it can happen for a few reasons. For example, on Windows 2019 server, someone installed Ultravnc 1.4.3.6 but got a black screen. This could be related to display driver problems on the remote computer, or perhaps the VNC server isn't capturing the display output correctly. Ensuring your Ultravnc viewer and server versions are the same can sometimes help, as can restarting the Ultravnc service or checking the remote PC's display settings. It's one of those things that usually has a straightforward fix, if you know where to look, that is.
Does Ultravnc support remote desktop audio?
