Step 3: Troubleshooting Common Issues

While the installation usually proceeds smoothly on Windows Server 2016, you may encounter specific errors.

Step 2: Pre-Installation Check (Optional but Recommended)

Sometimes, a pending reboot can block the installation. It is best to ensure there are no pending Windows Updates or restarts waiting to be processed.

  1. Open Server Manager.
  2. Check if a restart is required (usually indicated by a warning icon or notification).
  3. Restart the server if necessary before proceeding.

Method 3: Deployment via Group Policy or SCCM

  1. Create a shared network folder with read access for all target servers.
  2. Place the offline installer there.
  3. Create a startup script (batch or PowerShell) that runs the silent command.
  4. Link the script via Group Policy: Computer Configuration → Windows Settings → Scripts → Startup.

2.2 Security & Cryptography

| Feature | Benefit on Server 2016 | |---------|------------------------| | TLS 1.2 / 1.3 (where OS supports) | Default secure protocols for HttpClient, SmtpClient | | SHA-2 only mode | No SHA-1 by default; strengthens code signing & cert validation | | CNG Cryptography Next Generation | Full support for elliptic curves (ECDSA, ECDH) | | Signed XML (XmlDsig) improvements | Supports modern algorithms for SAML, WS-Security | Method 3: Deployment via Group Policy or SCCM

Plan for the Future

While 4.8 is stable, new applications may eventually require .NET 6/8/9 (the "Core" family). Those run side-by-side with 4.8, so you can have both. Just remember: .NET Core runtimes are distributed separately and also have offline installers.

Step 4: Running the Installation (Command Line / Server Core)

If you are running Windows Server 2016 Server Core (no GUI), you cannot double-click the installer. You must use the command line.

  1. Open Command Prompt or PowerShell as Administrator.
  2. Navigate to the directory containing the installer using the cd command. 
    cd C:\Install
  3. Run the installer silently. The /q switch runs it in quiet mode (no user interaction), and /norestart prevents the server from rebooting immediately (allowing you to schedule the reboot). 
    ndp48-x86-x64-allos-enu.exe /q /norestart
  4. Monitor the process in Task Manager. Once the process disappears from the background processes list, the installation is complete.
  5. Reboot the server manually: 
    shutdown /r /t 0
