Installing SharePoint 2010 Without Internet Access

Recently, I was forced to install SharePoint 2010 on a network without internet access. Due to the fact that SP2010 requires about a dozen prerequisites, this is much more difficult than it should be.
There is a way to set up the installer to not attempt to access the internet to download the prerequisites.
First, You'll need a computer that has internet access so that you can download the prerequisites.
Fortunately, someone did the work for me to do this part.
The SharePoint PowerShell script to download all the prerequisite files

SharePoint can be downloaded as an ISO from Microsoft. You'll need to get this and copy all the files into a directory somewhere. Put all the prerequisite files in the ""PrerequisiteInstallerFiles" folder.
This list assumes you are installing on Server 2008 R2. Server 2008 has some slightly different items and hotfixes

Next, create a file called: "PrerequisiteInstaller.Arguments.txt". Open it up in notepad and add:

/SQLNCli:PrerequisiteInstallerFiles\sqlncli.msi /ChartControl:PrerequisiteInstallerFiles\MSChart.exe /IDFXR2:PrerequisiteInstallerFiles\Windows6.1-KB974405-x64.msu /Sync:PrerequisiteInstallerFiles\Synchronization.msi /FilterPack:PrerequisiteInstallerFiles\FilterPack\FilterPack.msi /KB976462:PrerequisiteInstallerFiles\Windows6.1-KB976462-v2-x64.msu /KB976394:PrerequisiteInstallerFiles\Windows6.0-KB976394-x64.msu /ADOMD:PrerequisiteInstallerFiles\SQLSERVER2008_ASADOMD10.msi /Speech:PrerequisiteInstallerFiles\SpeechPlatformRuntime.msi /SpeechLPK:PrerequisiteInstallerFiles\MSSpeech_SR_en-US_TELE.msi /ReportingServices:PrerequisiteInstallerFiles\rsSharePoint.msi


NOTE: This should all be on one line! No New lines!


When you run the SharePoint setup.exe, it'll run the PrerequisiteInstaller.exe which will read the arguments file, and load the files from the prerequisites installer directory instead of trying to go to the internet!
