How to Mount ISO Files on Windows Server 2008 R2 with Native Tools and PowerShell


7 views

Windows Server 2008 R2 lacks native ISO mounting capabilities present in later Windows versions. While third-party tools like Daemon Tools often work on client OSes, enterprise environments frequently block such software due to security policies or driver signing requirements.

# PowerShell 2.0 method using COM object
$isoPath = "C:\install\server2016.iso"
$mountResult = (New-Object -ComObject IMAPI2FS.MsftFileSystemImage).Load($isoPath)
$driveLetter = (New-Object -ComObject IMAPI2.MsftDiscMaster2).Item(0).Mount($mountResult)
Write-Host "Mounted to $driveLetter"

For ISO files containing Windows images specifically:

Dism /Mount-Image /ImageFile:C:\images\install.wim /Index:1 /MountDir:C:\mount

Microsoft's official solution for datacenter environments:

  1. Install Hyper-V role
  2. Create virtual machine without OS
  3. Attach ISO as virtual DVD
  4. Access through VM console or network share

Add this REG file to enable right-click mount (use at your own risk):

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.iso\Shell\Mount]
@="Mount ISO"

[HKEY_CLASSES_ROOT\.iso\Shell\Mount\command]
@="powershell.exe -nologo -noprofile -command \"$img = New-Object -ComObject IMAPI2FS.MsftFileSystemImage; $img.Load('%1'); $drive = (New-Object -ComObject IMAPI2.MsftDiscMaster2).Item(0).Mount($img)\""
  • Error 0x80070490: Usually indicates missing IMAPI2 components - install KB982018
  • Access Denied: Run PowerShell as Administrator with Set-ExecutionPolicy RemoteSigned
  • 0x80070002: Corrupt ISO file - verify checksums

Windows Server 2008 R2 lacks native ISO mounting capabilities that were introduced in later Windows versions. While Windows 8/Server 2012+ includes built-in Mount-DiskImage PowerShell cmdlets, Server 2008 requires alternative approaches.

For environments where installing third-party software isn't possible due to security policies, consider these native methods:

# Option 1: Using IMAPIv2 via VBScript
Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.Namespace("C:\path\to\iso")
Set objFolderItem = objFolder.ParseName("image.iso")
objFolderItem.InvokeVerb("Mount")

For administrators preferring PowerShell, here's a script that leverages the Virtual Disk Service:

# PowerShell ISO Mount Script for Server 2008
$isoPath = "C:\install\windows.iso"
$vdsService = New-Object -ComObject "Vds.ServiceLoader"
$vds = $vdsService.LoadService("")
$vds.WaitForServiceReady()
$vdsDisk = $vds.GetDiskFromFileName($isoPath)
$vdsDisk.Mount($true, 0)

When third-party tools are permitted, these reliable options exist:

  • Virtual CloneDrive (lightweight, no reboot required)
  • WinCDEmu (open-source alternative)
  • PowerISO (commercial solution with CLI support)

For repetitive deployment scenarios, create a batch script combining diskpart:

@echo off
echo select vdisk file="C:\isos\deploy.iso" > mount.txt
echo attach vdisk >> mount.txt
diskpart /s mount.txt
del mount.txt

When encountering "Access Denied" errors:

  1. Verify Administrator privileges
  2. Check NTFS permissions on the ISO file
  3. Ensure no conflicting drives (map to unused drive letter)
  4. Confirm ISO file integrity (SHA-1 checksum)

Always validate ISO files before mounting:

Get-FileHash -Algorithm SHA256 C:\isos\download.iso

Compare against published checksums from trusted sources.
