Hi EE

Does anyone have a PS script to share that would scan a list of servers and check for open shares and report on them ? either to just report the server it found an open share on or the share that is open to everyone .

Thank you all for your help ..

Miles,

you can specify the OU where the computer / servers located with the below powershell script:

Modify line 4,5 and 6 according to your OU in AD or even just remove line 5 and 6 if you only have one location for the OU to be scanned.
The result will be in in Line 9

#OU Locations, make sure the index is in order, 1, 2, 3, etc. 
#you cannot have 3 without 2, etc. 
$ous = @{} 
$ous[1] = 'LDAP://OU=Branch Office Servers,OU=Servers,DC=domain,DC=com' 
$ous[2] = 'LDAP://OU=Test Server,DC=domain,DC=com' 
$ous[3] = 'LDAP://CN=Computers,DC=domain,DC=com' 

#set logfile directory 
$script:logfile = "C:\TEMP\everyoneshares.txt" 

#This pulls all computer accounts from AD 
function getresults($path,$cert) { 
	$objDomain = New-Object System.DirectoryServices.DirectoryEntry 
	$objSearcher = New-Object System.DirectoryServices.DirectorySearcher 
	$objSearcher.SearchRoot = New-Object System.DirectoryServices.DirectoryEntry($path) 
	$objSearcher.PageSize = 1000 

	# How many to retrieve at a time. Not output size. 
	$objSearcher.Filter = $strFilter 
	$objSearcher.PropertiesToLoad.Add("cn") >$null 
	$colResults = $objSearcher.FindAll() 

		foreach ($objResult in $colResults) { 
			$objItem = $objResult.Properties 
            $computer = $objItem.cn[0] 
			$computer = $objItem.cn 
            $script:comps += $computer 
		} 
} 

#This runs the getresults function for each OU supplied above 
$script:comps = @() 
foreach ($ou in 1 .. $ous.Count) { 
	if ($ous.$ou) { 
		$strFilter = "(&(objectClass=Computer))" 
		getresults $ous.$ou 
	} 
} 

$comps = $script:comps | Sort name 
$script:mylist = @() 
write-host `n 

foreach ($comp in $comps) {
#1 
	#here's where we actually pull each share from the current computer 
	$shares = gwmi Win32_LogicalShareSecuritySetting -co $comp -erroraction silentlycontinue | ? {$_.Name -notlike "*$"} 
    if ($shares) {
	#2 
		foreach ($share in $shares){
		#3 
			$SecurityDescriptor = $Share.GetSecurityDescriptor() 
            ForEach ($DACL in $SecurityDescriptor.Descriptor.DACL) {
			#4 
				$myshare = "" | Select Server, Share, ID, AccessMask 
				$myshare.Server = $comp 
				$myshare.Share = $share.name 
				$myshare.ID = $DACL.Trustee.Name 
				Switch ($DACL.AccessMask) {
				#5 
					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} 
				}
				#5 
				$myshare.AccessMask = $AccessMask 
				if (($AccessMask -eq "FullControl") -AND ($myshare.ID -eq "Everyone")){
					$script:mylist += $myshare
				} Clear-Variable AccessMask -ErrorAction SilentlyContinue 
			}#4 
		}#3 
	}#2 
}#1 
$mylist | out-file $script:logfile 
$count = $mylist.count 
write-output `n "found $count shares where Everyone was given FullControl" | out-file $script:logfile -append write-host `n
