I've had a bit of a battle getting PowerShell to work on creating remote shares with the permissions I want. I think I have it working now in a fairly minimalist fashion.

    #create a share using WMI and PowerShell

    #

    #To create a share with PowerShell utilizing WMI (so you don't need

    #to use PSRemoting) you need to do the following:

    #1) Create the Win32_Share class

    #2) Create the Security Descriptor for the share

    #3) Create the ACE for the share

    #4) Create the Trustee fo rthe ACE

    #5) Set all the variables

    #6) Create the share.

    #

    #The next lines sets a computer (%cn%) to "EVERYONE FULL CONTROL" on the

    #share "HomeDirs"

    $cshare = [WMIClass]"\\%cn%\root\cimv2:Win32_Share"

    $securityDescriptor = ([WMIClass] "\\%cn%\root\cimv2:Win32_SecurityDescriptor").CreateInstance()

    $ACE = ([WMIClass] "\\%cn%\root\cimv2:Win32_ACE").CreateInstance()

    $Trustee = ([WMIClass] "\\%cn%\root\cimv2:Win32_Trustee").CreateInstance()

    $Trustee.Name = "EVERYONE"

    $Trustee.Domain = $Null

    $Trustee.SID = @(1, 1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0)

    $ace.AccessMask = 2032127

    $ace.AceFlags = 3

    $ace.AceType = 0

    $ACE.Trustee = $Trustee

    $securityDescriptor.DACL += $ACE.psObject.baseobject

    #trying to create share...  variables are:

    #,,,(if $Null set to maximum allowed),,,

    $result = $cshare.create("%homeDrive%:\homedirs","homedirs",0,$Null,"Home Directory Share",$Null,$securityDescriptor)

   

}

Enjoy!
