Installing Skype for Business Server on Windows 2016 without Internet access

By | January 18, 2018

So we have all read the Microsoft support article on how to install Skype4B on Windows Server 2016, but if not. Heres a summary.

  • Run the installer
  • Download and install updates
  • Finish running the installer
  • Continue as normal

That’s all fine and dandy. But what about in hardened environments where the Skype4B servers don’t have access to Microsoft Update/Wsus?

Simple, We cache the patches on a staging machine first and transfer the files using your preferred method.

  • On your staging machine, Run Setup\amd64\Setup.exe from your Skype4B installation media.
  • When the installer starts you will be prompted to download updates. Download and install these.

  • Once the installer has downloaded and cached all the files on your staging PC, and you press next, it will install a few more bits then open the Deployment Wizard
  • Close the Deployment Wizard

  • Now On the machines without internet access, run the installer, but don’t select to download updates.
  • Once the installer completes caching files and opens the Deployment Wizard, Exit
  • On your staging machine navigate to C:\ProgramData\Microsoft\Skype for Business Server\Deployment
  • There should be a folder here called patchcache 
  • Copy the patchcache folder to your target server in the same location (it will only have a cache folder)

Staging Server

Target Server

  • From the start menu on the target server navigate to “Skype for Business Server 2015 > Skype for Business Server Deployment”
  • Run the Deployment wizard as normal.

  • When you install the roles, you will notice the bootstrapper finds and uses the MSP files located in Patchcache to patch the MSI files post installation
  • In some cases you may be asked to reboot. This is normal



Hope this helps someone.
