Troubleshooting Error Code 0x800f0950 on Windows Server 2019

To resolve the error code 0x800f0950 in Windows Server 2019, which typically occurs during the installation of roles and features, follow these steps:

1. Update Your Server: Ensure that your server is up to date with all the latest updates and patches. Access Settings > Update & Security > Windows Update and select 'Check for updates'.
2. Utilise the DISM Tool: Open Command Prompt as an administrator and execute: DISM /Online /Cleanup-Image /RestoreHealth. This command helps repair corrupted system files that could be causing the installation error.
3. Verify Source Files Accessibility: Ensure that the source files needed for the installation of roles and features are available and can be accessed. If you are using a network share, confirm that it is accessible and that you have the appropriate permissions to access it.
4. Temporarily Disable Antivirus Software: Antivirus programs can sometimes obstruct the installation of new software. Disable your antivirus temporarily and attempt the installation again.
5. Use Server Manager for Installation: Instead of using command-line tools like PowerShell or DISM, try installing roles and features through the Server Manager. Open Server Manager, select the server on which you wish to install roles and features, and proceed by clicking 'Add roles and features'. Follow the instructions provided by the wizard to complete the installation.
