PowerShell: Inter-Domain SMB Shares Mounting

# interDomainFileCopy.ps1
# Note: this is a quick and dirty method. Password security must be handled to substitute the $plainTextPassword variable.

$computerName="SOMESERVER"
$username="RAMBO"
$plainTextPassword="whatpassword?"
$driveLetter="x:"

try{ 
    # wrap powershell around the venerable command 'net use' that is more reliable than the New-PSDrive cmdlet
    invoke-expression "net use $driveLetter '\\$computername\$shareName' /user:$userName '$plainTextPassword' /persistent:Yes" -ea Stop
    # only proceeds if there're no errors in the previous command
    robocopy '$driveLetter\' c:\backups\$computername /E /R:0 /NP
    # optional: remove the mount when done
    # net use x: /delete
    }

    throw $_
