PowerShell Import Shares and Security info From CSV

---

---

this Powershell scipt will import the shares from the CSV file created in the first part of this serie : PowerShell Export Shares and Security info to CSV .

For this example let's asume that we have 2 shares : Foo and Bar

so listing the shares will give this output :



on both we have everyone read and on the Share Bar I added MOW with Full Control

and did we run the script in the first post in this serie and exported them to a CSV file, the file would look like this :



we can check the rights by using the FileSystemRights Enum :



(note share security is a bit different from filesystemsecurity so the reading is a bit different Replace Security on existing share using MSH)

now we want to re-create the shares

I will first show some parts of it from the CommandLine and then show the complete script (the compete script can be pasted to the commandline also) :

first we get the CSV file into an PSObject again



as we only can create the share one time but there could me more entries for a share in the script I loop only trough the shares on the commandline it looks like this :



you can see how get a list with every share only one time, so I can loop trough it to make the shares.

for each share in the loop I find only the rows of the second share and I do another loop (on the commandline Example I hardCoded Bar)



Next I need to convert the textform SID into a Binary SID again,
therefore we can use the securityidentifier .NET class ( for more info see :
Get Binary SID in MSH (Share Security Update))

an commandline example for one SID :



(there are also examples on my blog to translate the SID object to a user, try a search for SID on my blog for this)

the making of the trustee and ACE'es are the same as in the change share security sample so I will not further go into it here,

only you may note that I do this for the name property only :

$Trustee.get_Properties()['name'].set_Value($_.domain)

this is becouse there is a AliasProperty Name Defined that overrules the Original Name property of the win32_trustee Class in the typedata of PowerShell RC1, I will file this as a Bug on Connect.

the calling of the create method I did from an template I did create with the get-WmiMethodHelp script from this post : MSH get-WmiMethodHelp function Update 3 and did fill in.

note the use of $sd.PsObject.BaseObject
(if you forget this PowerShell will give a confusing error)

The Complete script looks like this :



And we can use it like this :




you can see the shares are recreated with the right securitym and a return value is returned to check if it want OK (a 0 means OK a 22 share does exist allready).

if you want to know the other returnvalues you can look at the get-WmiMethodHelp script output also :





Enjoy,

PS. as Blogger had problems and my first post failed my post is messed up by BLogger,
so the formatting is messed up and you may miss some pipeline symbols (and and of lines when pasting, sorry for that,
but I RePasted the complete script again into the post so that should not give problems when pasted in the the powerShell
