Patch Installation using Power. Shell, VBScript and PSExec | Learn Powershell. In my current environment, I am one of many people in our shop that carry the same task as many of you. That task is to patch our systems to ensure we keep ourselves up to date on the latest security updates. This can be done many different ways from manually downloading and installing patches, setting deadlines in WSUS to complete the installations, managing the installations via Group Policy to name a few of the possible scenarios. Another way that I will show you combines a melting pot of technologies using Power. Shell, VBScript and PSExec. If you have seen my other function, Get- Pending. Updates and its associated blog posting here, then I would consider this the partner module to that. VB…What?!? Ok, you might be asking me: “Boe, why would we use this old legacy scripting language when we have the awesomeness that is Power. Shell?” Good question! Adding a DNS A record to a Win 2008R2 server from an Win 2008R2 server or Win7 via Powershell. you get the powershell server admin modules available. DHCP. 3.
The answer to that is that while we do have Power. Shell which makes our jobs and life soooo much easier, most of us simply do not have it installed on every system, or some systems older and cannot have Power. Shell installed on them. Hence, we have VBscript which bridges that gap and gives us a scripting language that works on legacy systems all the way up to our Win. Monthly Archives September 2015. This script also requires the FTP for powershell module. Download the. //gallery.technet.microsoft.com/scriptcenter/PowerShell. A simple search of TechNet for 'powershell dhcp' will. download Windows PowerShell 3.0 from the Microsoft Download. also remember that the scripting games are. K8. R2 systems. The trick to this is that instead of having a vbscript file to copy each time, I simply use a here- string to contain the code and then use Out- File to write the vbscript to the remote machine. This also makes this code more portable as you only have one file to deal with as opposed to multiple files. The Module. I decided to go with a module so I can only export the one function I need while leaving the other functions that do the background work hidden. With that in mind, when you copy the code you must save it with a . Import- Module cmdlet. Microsoft and Docker. The Windows Holographic SDK and emulator are now available for download and Microsoft. as do gaming companies like SuperGiant Games. Import-Module : The specified module 'activedirectory' was. Modules_ModuleNotFound,Microsoft.PowerShell.Commands. http://www.microsoft.com/en-us/download. I wrote the module so that you can supply a collection of computers if needed and it will do all of the processing of each system itself. You will need to download PSExec from here and place it in the same directory from where ever you are calling the function from. The Install- Patches function is the only visible function that you have available to run, but there are a total of 3 functions that are available within the module (Install- Patches,Create- Update. ![]() Powershell 5.0 Download Windows 10VBS and Format- Install. Patch. Log). It will then call the Create- Update. VBS function to use the hardcoded Here- String of the vbs code and use the Out- File cmdlet to create the required Update. I cannot take credit for most of this vbscript as it was created by Microsoft and is available to view from their site here. I say most because I did make some adjustments to make it more Power. Shell friendly such as writing out the log file to a CSV instead of a text file. I also made some adjustments such as accepting a EULA if needed for an update prior to installing. I also took out the downloading of updates as well since they will have already been downloaded to the machine from WSUS (or downloaded if set up to do so on your computer to do so automatically). After the file has been created successfully, the Install- Patches function continues on and uses PSExec to remotely (or not remotely if running against your local machine) install the patches. I chose this route as I have not found a feasible way to remotely install patches. Using a WMI method with the Win. Process and Create method does not work and neither does Power. Shell remoting. This is a “by design” feature of the COM object and does not look to be changed any time soon. PSexec is my best approach at working around this obstacle. After the Update. CSV file is created either showing what patches were installed or showing that no patches were installed for one reason or another. After PSExec runs, I then check the value of $LASTEXITCODE, which tells you the return code of the application that ran with a 0 being successful. LASTEXITCODE is described as: Contains the exit code of the last win. If no issues are encountered with PSExec, then the next function that is called is Format- Install. Patch. Log which takes the created CSV file and makes a couple of adjustments to the log file before presenting it as the output object. Module in Action. Ok, enough talk about the module itself and now onto the actual module in action. The first thing I do is import my module into the Power. Shell console using the following line of code: Import- Module Install- Patches. Force. I use the –Force switch because I already had the module imported and wanted to “overwrite” the existing function. I say “overwrite” because if you run the command while with –Verbose, you will see that it actually removes the existing function before adding the new function. The next step is to make sure that you are in the same directory as PSExec. Ok, lets actually run the function against a remote system and see what happens. Install- Patches - Computername DC1. As you can see, the PSExec operation took place against DC1 as expected and the reporting object was also returned which is good. Looking at this, we can see that the Install. Result. Code is reporting that a reboot is required to complete the patch installation. This is by design that the installation does not automatically reboot the system. It is important to keep in mind that if there are more patches, then it will take longer to run through the installation of each patch. This function does accept a collection of systems and also accepts those from the pipeline as well which allows you some flexibility in how you would like to run the command. There may be instances when a result code is not displayed or says “Unable to determine Result Code”. This means that the result code returned from the script could not be decoded by the function. That is not to say that the code can never be figured out, it is that I chose to not include the hundreds of possible codes in the script. If you would like a listing of all of the codes to search from, you can find that here. With that, you can see how this might prove useful to you based on your environment. You could pipe the results into a CSV file if you wanted something to email folks with. This also makes it easy to determine if any patches failed or which systems would need to be rebooted after the installations. You can even use Get- Pending. Updates as an extra measure to make sure no other patches have snuck in and need to be installed. Code. As always, the code is available to copy from either here or from the following locations: Script Repository. Posh. Code< #. Save this with a .

Bu bölümde, Windows Powershell 3. Active Directory kurulumunu nasıl yapacağımızı anlatacağız.İlk olarak Windows Powershell ile alakalı kısa bir kaç açıklama yapalım. Microsoft çıkartmış olduğu ürünler de sürekli olarak komut satırından ziyade grafiksel arayüze daha fazla yoğunlaşmıştır. Tabi ki bu, ürünlerde komut satırının olmadığı veya scriptinguygulamalarının yapılmadığı anlamanına gelmemektedir. Daha önceki ürünlerde Netsh, Windows Script Host(WSH), Windows Management Instrumentation(WMI) gibi komut yazım dilleri bulunmaktaydı. Ancak bunlar belirli bir yere kadar basit konfigürasyonlara destek verebiliyordu. Sunucularüzerinde daha gelişmiş ayarların yapılabilmesi için Microsoft, Windows Power. Shell’i çıkardı. Windows Power. Shell bir komut satırı uygulamasıdır. Komut satırı kullanıcıları ve script yazarlarına . NET Framework gücünü veren bir ortamıdır. Power. Shell, bu konuda bildiklerimizin üstüne daha fazlasını eklemek, Windows komut satırı ve Windows Script Host(WSH)ortamları içinde oluşturulan scriptleri etkinleştirmede bizi çok sayıda yeni güçlü konseptlerle tanıştırmaktadır. Bu şekilde öğrendiğimiz bilgileri de daha fazla güncelleyebilme imkanı bulmaktayız. Windows Power. Shell, IT Profesyonelleri , programcılar ve Windows. Power Shell ile ilgili hiç bir ön bilgiye sahip olmayanlara kullanıcılara yöneliktir. Power Shell’i öğrenmek için scripting’deki ve WMI’daki birazcık ön bilgi yardımcı olmaktadır. Ancak bunun tam tersine, öğrenmek için de daha önceden bir scripting alt yapısınasahip olmak gerekmemektedir. Bu makalemizde , Powershell 3. Active Directory, Domain Controller kurulumunu hem katılımsız hem de otomatik olarak gerçekleştireceğiz. Windows Powershell 3. Windows Server 2. Active Directory Kurulumu.
