1. Current Issues
Because you want to build an AD domain controller, you need to install .NET3.5, but an error was reported when installing this function
Two, the solution
Since Windows server 2019 installs .NET4.7 by default, there will always be a mess of errors during the installation of .NET3.5. The current solution to this error is as follows:
1. Mount the current system image first
2. Open the image file, open the path X:\sources\sxs (X represents the drive letter where the image is mounted) and copy the path
Or you can copy and paste the sxs file to the local disk, and then select the path to the file
I have published the required files to the resources~~
3. Reinstall the corresponding function
Then in the next step, specify an alternate source path and select the path of the sxs file just copied
4. Complete the installation
