Question

Dear Team,

Kindly help.

Answer 1

Try the following

---

1. Review Installation Logs

• Examine the log files for more detailed error information:
  • DISM Logs: Located at C:\Windows\Logs\DISM\dism.log.
  • CBS Logs: Located at C:\Windows\Logs\CBS\CBS.log.
• Look for error codes or descriptions related to IIS installation failures.

2. Check Dependencies

• IIS relies on several dependent features to install successfully. Ensure these features are enabled:
  • HTTP Activation
  • .NET Framework 4.8 Features
  • Windows Process Activation Service
• Install dependencies manually:

       Install-WindowsFeature Web-Server -IncludeAllSubFeature
  

---

3. Clear Component Store and Rebuild

• If there’s an issue with the component store even though DISM reports no corruption, clearing and rebuilding it might help:

       DISM /Online /Cleanup-Image /StartComponentCleanup
       DISM /Online /Cleanup-Image /RestoreHealth
  

• Then retry installing IIS.

4. Install Using a Specific Source

• Missing or corrupted feature files may prevent installation. Use an alternative source from the installation media:
  1. Mount the Windows Server 2022 ISO.
  2. Locate the Sources\SxS folder on the mounted ISO.
  3. Run the following command to install IIS from the ISO:

             Install-WindowsFeature Web-Server -Source D:\Sources\SxS
     

     Replace D: with the drive letter of your mounted ISO.

5. Verify and Reset Server Manager

• If Server Manager is not working correctly:
  1. Reset the Server Manager feature installation cache:

             Remove-Item -Path C:\Windows\System32\ServerManager\ComponentConfiguration\* -Force
     

  2. Restart the server and try again.

6. Check Group Policy

• Ensure no Group Policies are preventing the installation of IIS. Check if the following policies are configured:
  • "Do not allow installation of features on demand"
  • "Specify settings for optional component installation"
• Run gpedit.msc to check or confirm using:

       Get-GPO -All | Select-String -Pattern 'Feature' -CaseSensitive
  

---

7. Temporarily Disable Antivirus or Endpoint Protection

• Some antivirus or endpoint protection software might block certain operations during feature installation. Temporarily disable them and retry.

---

8. Repair/Upgrade Installation

• If none of the above steps work, an in-place upgrade/repair of the Windows Server installation might resolve deeper system issues:
  1. Boot from the Windows Server 2022 installation media.
  2. Select the Repair your computer option and choose to keep settings and features.
