I need to install ConfigMgr on a server that doesn’t have Internet connectivity. Is there a way I can download the ConfigMgr pre-requisite files on a machine that does have Internet connectivity and then copies these over to the target machine then point Setup at this directory?

Yes you can, but not only for the case you mention above but also to save bandwidth/ having to download the prereqs for every installation you do.

IMPORTANT: Bear in mind that Microsoft can change versions/ pre-reqs from time to time so it would be worth re-downloading the pre-reqs every so often to make sure you’re as up to date as possible.

To download the Prereq files manually before running ConfigMgr setup:

1. On the machine that has Internet connectivity create a directory to hold the Prereq files.

2. Insert the ConfigMgr CD.

3. From a Command Prompt navigate to the “\SMSSETUP\BIN\I386” directory on the ConfigMgr CD.

4. Type the following command:
   
   setup.exe /download <drive>:\<directory you want to use to store the prereq files>
   
   for example:
   
   setup.exe /download c:\configmgrprereqs
   
   You should then see the “Downloading updates” screen as shown below:
   
   
   
   
   Once the download has completed you will see the following screen:
   
   

5. Click “OK” to close the “Success” dialog box.

6. Copy the files onto the target machine.
   
   TIP: Open "ConfigMgrSetup.log" in the root of the drive from where you are running the command to monitor progress.
