Error 10054,
Cannot connect remotely to SQL Server Express Win 11, A network-related or instance-specific error

ADDITIONAL INFORMATION
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)

Got the same issue on a Windows 11 computer trying to connect to an old SQL 2005 DB. It looks like some ciphers are disabled on Windows 11 and prevent the connection with the Database.

Solution

In Powershell (as admin) after running the following command, I could connect to the DB. Hope this helps.

Enable-TlsCipherSuite -Name "TLS_RSA_WITH_3DES_EDE_CBC_SHA"

Copy and paste the above command in powershell, it will work for you.

It’s a common error that users face if a third-party printer driver is installed on the print server. Fortunately, you can fix this by following some simple steps.

Printer Error 0x00000040 can be fixed by following some simple steps.

What causes Operation could not be completed (error 0x00000040)?

Windows 10/11 doesn’t allow users to install a third-party printer driver on the print server. You need to change the Group Policy settings or tweak the Registry to resolve the issue. The other reasons for this error could be:

1.Point and Print Restrictions policy
2.Pending print jobs in Print Spooler
3.Printer Driver issues.

Run Printer Troubleshooter

1. Press Windows Key + I to open Settings.
2. Scroll down and select Troubleshoot > Other Troubleshooters.
3. Click on Run beside Printer.
4. Once the process is complete, restart your device to see if the printer error has been resolved.

Modify Group Policy Settings

Kernel-mode drivers operate in kernel mode and have unlimited access to hardware and memory. But sometimes, the kernel-mode driver’s policy can malfunction due to corrupted drivers. Disable the policy and check if the error is fixed.

Disable the Point and Print using Registry Editor

1. Press the Windows key + R to open the Run dialog box.
2. Type regedit and hit Enter.
3. Navigate to the following path :HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows NT\Printers\PointAndPrint

4. right-click on InForest and select Modify.
5. Now enter the Value data as 0 and click Ok to save the changes.
6. In the same way, change the value data of Restricted and TrustedServers to 0.
7. Close the Registry Editor and restart your computer.

Update Printer driver

Update your Printer driver and see. Keeping your drivers up-to-date is very important. Although Optional Updates do update some of the drivers, some require you to download the driver manually from the manufacturer’s website.

Microsoft will allow device manufacturers to disable the TPM requirement on their version of Windows 11 – you'll be doing the same here:
