Mass Printer Port Creation

Note: I'm a complete newbie when it comes to Powershell. I haven't even touched it prior to this week.

I need to create a bunch of printer ports (about 400). I found a script that will let me create one at a time and it works flawlessly (http://gallery.technet.microsoft.com/fc636246-c4a4-4aa1-b25d-ce2449b28a05). I have been trying to modify it so that I can import a list of IP addresses from a CSV file and step through the creation of each printer port. This has proven to be easier said then done.

My CSV File looks like this: 192.168.0.1,192.168.0.2, 192.168.0.3, etc etc...

My 'modified' script looks like this:
#Import the CSV list
$IPList=IMPORT-CSV C:\Users\administrator.AD\Downloads\portips.txt
#For testing Lists each item in the above file
#$IPList | FOREACH-OBJECT {$_}

FOREACH ($ip in $IPList) {
print $ip
#From Original Script - $ip = "192.168.0.1"
$port = [wmiclass]"Win32_TcpIpPrinterPort"
$port.psbase.scope.options.EnablePrivileges = $true
$newPort = $port.CreateInstance()
$newport.name = "$ip"
$newport.Protocol = 1
$newport.HostAddress = $ip
$newport.PortNumber = "9100"
$newport.SnmpEnabled = $false
$newport.Put()
}

When I run the original script it creates the one port. When I run my modified, it fails with the following error:
No file to print
Exception calling "Put" with "0" argument(s): "Invali
At C:\Users\administrator.AD\Downloads\test.ps1:30 ch
+ $newport.Put <<<< ()
    + CategoryInfo          : NotSpecified: (:) [], M
    + FullyQualifiedErrorId : DotNetMethodException

I'm guessing I'm making a newbie mistake, but I'll be darned if I can find a solution. Anyone able to help me out here? Thanks a bunch!

split on comma, but skip comma's for text encapsulated in quotations..

≫ Next: Distribute a script to the Servers in AD

≪ Previous: PS Script - Creating Multiple Printer Ports (Newbie Errors)

So I am using a simple split to split a string of text open..

$split = $output.split(",")

My problem is that sometimes comma's are part of the actual data, in those cases it will be surrounded by quotes.. so here would be a sample value I am splitting..

Warren, Harry,"Smith,Thomas",Johnson,Hardly

When I reference $output[2] I want it to equal "Smith, Thomas", not ""Smith"

≪ Previous: split on comma, but skip comma's for text encapsulated in quotations..

Hello,

I am a newbie in Powershell scritpting.

We have about 500 Servers with Windows Server 2003, 2008, and 2008 R2 in AD, and need to add to all of the servers a regsitry value to disble SSL2.0. I created a registry file to apply those servers, but I just wonder if there is a way that I can use a Powershell command to distribute this registry file (or a reg script) into the computers in AD.

Would you help me to figure this out?

Thanks in Advance.

error of new-pssession -authenticate CredSSP

≫ Next: Solved - How to take ownership and change permissions for blocked files and folders in Powershell

≪ Previous: How do you execute a exe file in PowerShell that is saved to a thumb drive?

I ran the following lines on both the client and server.

Enable-WSManCredSSP -Role client -DelegateComputer *
Enable-WSManCredSSP -Role server

Then the "new-pssession -authenticate CredSSP ..." command always returned:

"New-PSSession : [serverB] Connecting to remote server serverB failed with the following error message : There are currently no logon servers available to service the logon request."

Later I ran this command on the server side:

winrm quickconfig -transport:https -force

Then the "new-pssession -authenticate CredSSP ..." command always returned:

[serverB] Connecting to remote server serverB failed with the following error message : The WinRM client received an HTTP server error status (500), but the remote service did not include any other information about the cause of the failure.

I tried all kind of settings on both of the client and server but no any success. The PowerShell is V3. The client machine is a Windows 7 and the server machines I tried are Windows 2008 R2 and Windows 8 RP. All machines are in the same domain.

What else I can do? Thanks for any advice.

Solved - How to take ownership and change permissions for blocked files and folders in Powershell

May 25, 2012, 12:20 pm

≫ Next: Monitoring Long Running Scheduled Tasks

≪ Previous: error of new-pssession -authenticate CredSSP

Hello,
I was trying to take ownership & fix permissions on Home Folder/My Documents structures, I ran into the common problem in PowerShell where Set-Acl & Get-Acl return access denied errors. The error occurs because the Administrators have been removed from file permissions and do not have ownership of the files,folders/directories. (Assuming all other permissions like SeTakeOwnershipPrivilege have been enabled.

I was not able to find any information about someone successfully using native PS to resolve the issue. As I was able to solve the issues surrounding Get-Acl & Set-Acl, I wanted to share the result for those still looking for an answer.
----
Question: How do you use only Powershell take ownership and reset permissions for files or folders you do not have permissions or ownership of?
----

Problem:
Using the default function calls to the object fail for a folder that the administrative account does not have permissions or file ownership. You get the following error for Get-Acl:

PS C:\> Get-Acl -path F:\testpath\locked
Get-Acl : Attempted to perform an unauthorized operation.
+ get-acl <<<<  -path F:\testpath\locked
+ CategoryInfo          : NotSpecified: (:) [Get-Acl], UnauthorizedAccessException
+ FullyQualifiedErrorId : System.UnauthorizedAccessException,Microsoft.PowerShell.Commands.GetAclCommand

If you create a new ACL and attempt to apply it using Set-Acl, you get:

PS C:\> Set-Acl -path F:\testpath\locked -AclObject $DirAcl
Set-Acl : Attempted to perform an unauthorized operation.
At line:1 char:8
+ Set-Acl <<<<  -path "F:\testpath\locked" -AclObject $DirAcl
+ CategoryInfo          : PermissionDenied: (F:\testpath\locked:String) [Set-Acl], UnauthorizedAccessException
+ FullyQualifiedErrorId : System.UnauthorizedAccessException,Microsoft.PowerShell.Commands.SetAclCommand

Use of other functions like .GetAccessControl will result in a similar error: "Attempted to perform an unauthorized operation."

How do you replace owner on all subcontainers and objects in Powershell with resorting to external applications like takeown, icacls, Windows Explorer GUI, etc.?

Monitoring Long Running Scheduled Tasks

≫ Next: Execute user input in ScriptBlock

≪ Previous: Solved - How to take ownership and change permissions for blocked files and folders in Powershell

Hi Everyone!

I found a fantastic ps script that will monitor a long running scheduled task...the link is here: Original Script

After a bit of tweaking, I got this running perfectly...but can only set it up for watching one scheduled task. The script looks at the $server and pulls in the scheduled tasks information into a CSV and puts that CSV into the $scriptpath. It looks for the $scheduledtask value and if it exceeds the $maxminutes it sends an email. I'd like to be able to have the script look at several scheduled tasks but do not know enough about powershell to "loop" through a list of tasks and send an email out for any of those tasks that meets the criteria for sending an email alert.

So basically I need some help tweaking this script to monitor a few scheduled tasks instead of just one.

Thank you so much for looking at this with me. Here's the working script for monitoring one task:

$server = "Server_Name"
$scheduledtask="Test Task"
$maxminutes="5"
$scriptpath = "C:\Path_To\Script"

# Send email function

function sendEmail {

$from = New-Object System.Net.Mail.MailAddress "abc@def.com";

$to = New-Object System.Net.Mail.MailAddress "abc@def.com";

$mail = New-Object System.Net.Mail.MailMessage $from, $to;

$mail.Subject = "Scheduled Task ( $scheduledtask ) on $server has been running for longer than $maxminutes minutes.";

$mail.Body = "Scheduled Task ( $scheduledtask ) on $server has been running for longer than $maxminutes minutes. Total Runtime for ( $scheduledtask ): $datediff .";

# Connect to mail relay

$smtpserver = "smtp.server.com"

$smtp = New-Object System.Net.Mail.SmtpClient ($smtpserver);

# Send Email

$smtp.Send($mail);

}

schtasks /query /s $server /FO CSV /v > "$scriptpath\ScheduleTaskMon.csv";

$longrunning = Import-Csv "$scriptpath\ScheduleTaskMon.csv" |

Where-Object {[DateTime]$_."Last Run Time" -and $_."Status" -eq "Running" -and $_."TaskName" -eq "$scheduledtask"};

$datediff=([DateTime]::Now)-([DateTime]$longrunning."Last Run Time");

if ($datediff -le 0)

{exit}

if (($datediff.TotalMinutes) -gt $maxminutes)

{sendemail};

Execute user input in ScriptBlock

August 9, 2012, 10:07 pm

≫ Next: PS Remoting - Failed to connect to an IPC port: Access is Denied

≪ Previous: Monitoring Long Running Scheduled Tasks

So I am trying to get [1] this code to work. What I would like is to have is a script that, when run, asks for a command. I would enter the command I want run on the computers I specify, and the script would execute that command on computers in a remote session.

Right now, I either get an error (varies) or no error (but the code doesn't run). Here are the iterations of the specific line I have tried (with "$cmd" being the command to execute):

Invoke-Command -Session $session -ScriptBlock {$cmd}

Invoke-Command -Session $session -ScriptBlock {invoke-expression $cmd}

Invoke-Command -Session $session -ScriptBlock {$args[0]} -ArgumentList $cmd

I have also tried creating a ScriptBlock before hand using different commands, but no combination has worked. So far for all my searching I have yet to find someone discuss passing user input into "Invoke-Command." Everyone seems to only pass pre-defined commands, which I have no problems running.

Here is the code I am using:

#Get Credentials
$name = [System.Security.Principal.WindowsIdentity]::GetCurrent().Name
$cred = Get-Credential $name

#Get Computer(s)
$comp = read-host "Enter the computer name you would like to run commands on"

#Open Session with specified computer(s)
$session = New-PSSession -ComputerName $comp -Credential $cred

#Execute remote command
$cmd = read-host "Enter the command string to run"
Invoke-Command -Session $session -ScriptBlock {$cmd}

#Close Session
Remove-PSSession $session

In this instance I am trying to run the command "slmgr.vbs /ato" on the remote machine. I know that the command itself works when initiated manually. Do I need to escape the "/"? Also I have tried to use parameters and creating the ScriptBlock separately, but none of these things have worked. Thanks in advance.

PS Remoting - Failed to connect to an IPC port: Access is Denied

December 10, 2009, 11:10 am

≫ Next: Use Powershell to check whether and AD user exists

≪ Previous: Execute user input in ScriptBlock

I am trying to configure some deployment steps in our build process. This involves using powershell to remotely execute MSTEST.EXE. The remoting works fine for things like {Get-Process} or writing a file to the remote local drive. However, MSTEST fails with the following error:

Failed to connect to an IPC port: Access is Denied

The account that powershell runs under is a domain account, and is a local admin on both the local and remote boxes.

Script looks like:
==================
invoke-command -computername BUILD01 -scriptblock {
d:
cd "D:\BuildDrop\Testing_20091210.4"
$exe = "C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\mstest.exe"
$vsmdi = "D:\BuildDrop\Testing_20091210.4\Release\WebTests\MyProject.Tests.vsmdi"
& $exe /testmetadata:$vsmdi /testlist:AllWebTests

}
===================

I've tried using the -Credential option too, but that made no difference. I'm not sure what security to tweak where to fix this error.

Suggestions?

Use Powershell to check whether and AD user exists

≪ Previous: PS Remoting - Failed to connect to an IPC port: Access is Denied

We're trying to clean up roaming profile folders, and as part of the task I need to check whether the user actually exists in AD. I have tried 3 different methods and so far none of them work.

Either the empty result of the search doesn't equal $null (e.g. If ($objUser -eq $null) resolves to false) or Powershell crashes (like when I try to run that If statement). So is there an AD User equivalent to Test-Path?

Direct un-buffered writes in Powershell

August 22, 2012, 6:39 pm

≫ Next: Powershell Backup script, but leaves 12 files

≪ Previous: Use Powershell to check whether and AD user exists

Currently I am trying to run a test that will power-down the machine abruptly when a file is being written. When power-down occurs the last part of data is not present as it is never flushed to disk before power down.

Perl (in Linux) allows direct un-buffered writes when a file is opened in the following manner.

sysopen(F, $file, O_WRONLY|O_DIRECT) or die "Couldn't direct open file $file\n";

This allows data to be written till the last character in-case machine crashes due to some reason. Likewise, for windows, C++ allows direct writes when a file is opened for writes using "FILE_FLAG_NO_BUFFERING" flag.

How can I allow direct/un-buffered writes to disk using powershell ?

This for the case where backups stopped producing and we don’t want the last 12 to get deleted until there are newer.
