Installing .NET Framework 3.5.1 with MDT without Internet Connection

Setting the WindowsSource Variable

To install .NET Framework 3.5.1 without an internet connection, you need to specify the local source path in the `customsettings.ini` file. This ensures that MDT uses the local source files during deployment.

Steps to Configure MDT

1. Modify the customsettings.ini File

Open the `customsettings.ini` file located in the `Control` folder of your deployment share. Add or modify the `WindowsSource` variable to point to the location of your source files:

[Settings]
Priority=Default
[Default]
WindowsSource="%DeployRoot%\Operating Systems\ISO Windows 8.1\Sources\sxs"

This sets the source path for .NET Framework 3.5.1 installation files.

2. Update the Task Sequence

In the MDT Deployment Workbench, edit your task sequence to include the installation of .NET Framework 3.5.1. Add a step to install roles and features, specifying .NET Framework 3.5.1:

Steps:

• Right-click your task sequence and select Properties.
• Navigate to the Task Sequence tab.
• Add a new step: Install Roles and Features.
• Specify .NET Framework 3.5.1 as the feature to install.
