How Can I Export Share Permissions for each Server, from Server.txt Input File?

Posted on 2014-03-18
Last Modified: 2014-03-19
Firstly, I already have the NTFS permissions. I ONLY need the "Share" permissions.

I have been working to understand and manipulate this script from here [] to export all share permissions to an HTML file, per server. I understand that this script is not written to access an input file, so I have been implementing variations of the code to include these few lines as described here [], to force the Main Script to query the "servers.txt" file and loop through the whole script, then iterate for every servername in the servers.txt file. I will greatly appreciate help to understand exactly how to run this script against many servers. I tried to place this in my PS $Profile, then tried to use it as a ".ps1" file. I will be glad to concatenate in Excel if I need to work with a one-liner per server.

Also, of note is that when I initially ran this a few hours ago, it ran with no errors, then I noticed that the HTML file was created after I refreshed my $Profile by typing .$Profile at cmd prompt or by closing and restarting PS. But subsequently I noticed this line, which is coded in the script:

ERROR: cannot enumerate share permissions

It continued to output an HTML file (only for the local server) but only AFTER I refreshed my "$Profile".

Thank you!

500 points is the maximum.
I'm not quite clear, do you need a separate file for each server?

Yes sir, I would like to create one HTML report for each server, which lists all shares on said server. But maybe it makes more sense to create one HTML file that contains permissions for ALL servers in the servers.txt input file, as long as there is a separation header that indicates where one server stops and the next one starts.

The above script did output one HTML file named "SAL9001ShareReport.html", but only after I reloaded my PS profile, and now every time I close and restart PS, the same file is created...

$OutFileName = $env:COMPUTERNAME + "ShareReport.html"

I am attaching a copy of that output HTML file here.

Try saving the below as a .ps1 file.  Then run it.  It will query a file "serverlist.txt" for the list of servers.
$typehash = @{
    0 = "Allow"
    1 = "Deny"

$permhash = @{
    1179817 = "Read"
    1245631 = "Change"
    2032127 = "Full Control"

$head = @"

$body = @"

Edit:  BTW, thought I should mention that the above is a modification of code I posted in http:Q_28289529.html, which in turn was partially based on the link you provided.

footech.. thank you very much for your help with this! i am attaching a copy of one of the HTML files for your fans.

it works wonderfully! i love the clean appearance of your code as well.

it throws this message, but this is obviously related to many servers being unreachable for whatever reason.

do you think it will be feasible for me to wrestle with this to integrate the NTFS permissions as well with an additional column? i like the Get-ACL approach, but how much work do you think it would be to reach that goal?

can you tell me what "GetWMICOMException" is related to in this instance?

Get-WmiObject : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

"The RPC server is unavailable" error can be caused by a few reasons, including: 1) incorrect DNS info, 2) firewall blocking ports, 3) service not running, 4) maybe others.

The code really doesn't have any error handling.  About the most basic you could do is including the following inside the foreach loop, which would just test if the machine is pingable before trying to get share info.
If ( Test-Connection $server -count 1 -quiet )
  #do stuff

I see no reason why you couldn't add NTFS permissions, but it's not without its challenges.  One question that you would have to decide on is how would the data (the HTML tables) be formatted.  You might notice that the output of what I provided is a bit different than the output of the script in the link you provided.  From your first sample you can see that it groups all share permissions into one cell (and all NTFS perms into another), whereas mine creates a separate row for each share permission - this is more useful when exporting to a .CSV.  If you did the same thing for NTFS perms that could get pretty long.  It's going to depend on what will be useful for you.  Also, if I was going to rework the script to include NTFS perms, I would probably opt to also use PowerShell Remoting to make things easier and quicker.  So, overall it's not a trivial addition.
