Maybe the error 0x80073701 was triggered by some temporary server issues.
Go back to the Settings option, select Update, and Security, and click on Windows Update.
Press the Check for updates button, and try to update your Server again.
If the problem still persists, then restart your Server.
Run the Update Troubleshooter to encounter the issue:
Navigate to Settings, and select the Update and Security option.
Then on the left-hand panel, click on Troubleshoot option.
Click on View additional troubleshooters.
Locate and launch the Update troubleshooter.
Run System File Checker:
The error 0x80073701 might be caused due to a missing system file. So to resolve the issue, try System File Checker,
Open the Command Prompt with Admin rights.
Now, type the command given below,
Type sfc /scannow and press Enter to proceed further.
Note: Don't close the command prompt windows until 100% complete message verification is done.
Thus, when the process completes, you will be able to install IIS features on Windows Server and check whether the 0x80073701 error is resolved or not.
Run DISM Tool:
Type cmd in the Windows Start Search box.
Right-click on the Command Prompt and go with the option Run as administrator.

dism /online /cleanup-image /startcomponentcleanup
Nextly, restart your computer to take effect and check if the issue is resolved and whether you can install IIS features on the windows server or not.
Check Logs and Remove Patches:
You will have to check the CBS.log and remove the patches in this method to resolve the error 0x80073701.
The CBS.log is a file that includes logs about components when they get installed or uninstalled during updates.
The CBS.log file is located in the %windir%\Logs\CBS folder.
If you find any error, then re-install a particular file.
But, If there is no error in the CBS.log, you must execute the below command,
DISM /Online /Cleanup-Image /ScanHealth
This command can check for component store corruption. Hence when the command completes successfully, you will be able to install the IIS feature on your Windows Server.
I hope the above fixes help you resolve the error 0x80073701, and you can install IIS features to your Server.
