Whenever DaVinci Resolve notifies me that a new firmware is available for the Speed Editor, the following happens:
I open the DaVinci Control Panels software.
It shows up like this for a few seconds (at most) and then disappears (crashes):
I was unable to resolve this problem on my PC. Instead, I’ve installed the Control Panels application on a different computer, where it worked just fine:
Unfortunately this required installing DaVinci Resolve, too, which can take a while. It would be nice if Blackmagic made the Control Panels app available as a separate download.
This post is mainly meant to remind me to simply use this method the next time I want to do a firmware update. If you don’t like it, you can always try to get help on the official DaVinci Resolve forum.
The problem: You cannot access the SAMBA (SMB) shares on your QNAP NAS from the Windows File Explorer and after you tried, access to the web interface also stopped working. The NAS is still accessible from other PCs on the same network.
The reason: Windows will first try to connect to your NAS using your Windows login credentials. If this fails too many times and Network Access Protection on your NAS is enabled, your PC’s IP address will be banned:
You can see the failed login attempts in the System Connection Logs (if enabled for SAMBA):
There are many threads about this issue on the QNAP forum proposing various solutions, such as:
Creating a user account on the NAS with the same user name and password as on Windows.
Disabling Network Access Protection on the NAS.
Making all folders public.
Disabling all guest shares on the NAS to force Windows to show the network credentials dialog.
I tried a different solution which I found here. I left everything on the NAS unchanged. In the registry of my Windows PC, I enabled insecure guest logons for the SMB client. This allows the PC to connect to SAMBA shares which are not protected by a password (such as the Public folder on a QNAP NAS).
This registry setting can be found under Local Computer Policy -> Computer Configuration -> Administrative Templates ->Network -> Lanman Workstation -> Enable insecure guest logons:
Note: The description says that “if you do not configure this policy setting, the SMB client will allow insecure guest logons.” This was not true for me on Windows 11 21H2, the setting had to be explicitly enabled. On other PCs running Windows 10, the described behavior was correct and the entire problem never appeared.
Now (and after the IP ban period has expired, of course) it was possible to access the NAS through the file explorer. Clicking on a protected folder brought up the Enter network credentials dialog:
Why did this work? Apparently, Windows only tried to use the current user credentials once when connecting to the NAS and then used guest access. As this resulted only in a single failed access attempt, the PC’s IP address was not banned.
Buying Acer’s Predator Orion gaming PC is one way to get an RTX 3070 graphics card without paying absurd prices. However, it comes with a standard CPU cooler that is loud and not very effective.
I replaced it with a Xilence XC026| I4026 (Amazon.com / Amazon.de affiliate links), which led to a significant CPU temperature drop under load. While this doesn’t turn the PC into a quiet machine, the cooler can be installed without replacing the backplate.
All you have to do is modify the cooler itself by moving the two brackets that hold the large screws as shown below.
On one side you can remove the fan to fasten the small bracket screws. On the other side there is very little room (this is the only challenge with this procedure):
Follow the instructions that came with the cooler for the rest of the (simple) installation process.
