Windows 2008 r2 sysprep – A fatal error occurred while trying to sysprep the machine - Windows Could Not parse or process unattend answer file for pass

Windows 2008 r2 sysprep – A fatal error occurred while trying to sysprep the machine 

AND

 Windows Could Not parse or process unattend answer file for pass

When I run sysprep, I found an error message “A Fatal error occurred trying to sysprep the machine”

To solved this problem, I do a this workaround :

• Change registry key HKEY_LOCAL_MACHINE\SYSTEM\Setup\Status\SysprepStatus to 7

• Change HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform\SkipRearm to 1
• And then Delete the folder Panther.

• And then run sysprep again.

After reboot when the installation  through following error message

"Windows could not parse or process unattend answer file [C:\windows\Panther\unattend.xml] for pass [specialize]. A component or setting specified in the answer file does not exist"

do This:

1. Press SHIFT+F10 to open a command prompt
2. type regedit
3. in registry editor navigate to:
4. HKLM/SYSTEM/Setup/Status/ChildCompletion
5. if setup.exe is 1, change it to 3.
6. restart

Export and Import NTFS permission with Powershell from one domain to another

Steps:
Export Permissions
Modify the permissions.csv file - Change the domain name
Import permissions

Assumptions:
User name are same in both domains
Folder structure remains the same

Exports.ps1
Get-ChildItem "S:\Folder" -Recurse | ?{ $_.PsIsContainer } | %{
  $Path = $_.FullName
  # Exclude inherited rights from the report
  (Get-Acl $Path).Access | ?{ !$_.IsInherited } | Select-Object `
    @{n='Path';e={ $Path }}, IdentityReference, AccessControlType, `
    InheritanceFlags, PropagationFlags, FileSystemRights
} | Export-CSV "c:\temp\Permissions.csv"

Import.ps1
$par = Import-Csv -Path "c:\temp\Permissions.csv"

foreach ( $i in $par )
 {
 $path= $i.Path
 $IdentityReference= $i.IdentityReference
        $AccessControlType=$i.AccessControlType
        $InheritanceFlags= $i.InheritanceFlags
        $PropagationFlags=$i.PropagationFlags
        $FileSystemRights=$i.FileSystemRights
        echo $path $IdentityReference
        $acl = Get-Acl c:\temp
        $permission = $i.IdentityReference,$i.FileSystemRights,$i.AccessControlType
        $accessRule = new-object System.Security.AccessControl.FileSystemAccessRule $permission
        $acl.SetAccessRule($accessRule)
        #$objACE = New-Object System.Security.AccessControl.FileSystemAccessRule     ($IdentityReference, $FileSystemRights, $InheritanceFlags, $PropagationFlags, $AccessControlType)
        #$objACL.AddAccessRule($objACE)
        $acl | Set-Acl $path
