Server Shares for SOX audit

Would someone be able to assist in setting this script up for a multi domain environment?  Thank you.

$computers = Get-Content $loc\list.txt;

function Get-AllSharePermissions
 {
 param (
 [parameter(Mandatory=$true,ValueFromPipeline=$true)]
 [string]$computername
 )

$ShareSec = Get-WmiObject -Class Win32_LogicalShareSecuritySetting -ComputerName $computername
 $myCol = @()
 foreach ($ShareS in $ShareSec)
 {
 $SecurityDescriptor = $ShareS.GetSecurityDescriptor()
 ForEach ($DACL in $SecurityDescriptor.Descriptor.DACL)
 {
 $myObj = “” | select Computername, Name, Domain, ID, AccessMask, AceType
 $myObj.Computername = $Computername
 $myObj.Name = $ShareS.Name
 $myObj.Domain = $DACL.Trustee.Domain
 $myObj.ID = $DACL.Trustee.Name
 Switch ($DACL.AccessMask)
 {
 2032127 {$AccessMask = “FullControl”}
1179785 {$AccessMask = “Read”}
1180063 {$AccessMask = “Read, Write”}
1179817 {$AccessMask = “ReadAndExecute”}
-1610612736 {$AccessMask = “ReadAndExecuteExtended”}
1245631 {$AccessMask = “ReadAndExecute, Modify, Write”}
1180095 {$AccessMask = “ReadAndExecute, Write”}
268435456 {$AccessMask = “FullControl (Sub Only)”}
default {$AccessMask = $DACL.AccessMask}
 }
 $myObj.AccessMask = $AccessMask
 Switch ($DACL.AceType)
 {
 0 {$AceType = “Allow”}
1 {$AceType = “Deny”}
2 {$AceType = “Audit”}
 }
 $myObj.AceType = $AceType
 Clear-Variable AccessMask -ErrorAction SilentlyContinue
 Clear-Variable AceType -ErrorAction SilentlyContinue
 $myCol += $myObj
 }
 }
 Return $myCol
 }
