Automate Computer Name during OSD in Config. Mgr 2. 01. 2 with Power. Shell – System Center Config.

Mgr. There are various of methods out there today on how you can automate the process of naming computers during OSD. I’ve previously blogged about how to do it with VB script, you can find that blog here. In this blog post we’ll be renaming the computer based upon two critera. First we need to determine what computer model the OS is being deployed on. Secondly we want to name the computer by using the serial number and a suffix, e.

So the script works great on a single account (tested on user in csv file) but when doing it with the original csv file it does not update the info. PowerShell (including Windows PowerShell and PowerShell Core) is a task automation and configuration management framework from Microsoft, consisting of a command-line.

In this blog post I’m performing OSD on Dell systems, but the script can easily be modified to support other vendors. The script. We begin with populating two variables, $Computer. Model and $Serial. Number data from WMI. Then we create two if conditions depending on the computer model (in this case laptop or workstation).

In each if condition we combine $Serial. Number with a dash and at the end a suffix for either a workstation or laptop. We’ll then get something like 1. WS or 1. 23. 45. 67- LAP in the $OSDComputer. Name variable. Next we create a new COM object from the Microsoft.

SMS. TSEnvironment class. The value of $OSDComputer.

Name will then be put into the newly created COM object. Computer. Model = (Get- Wmi. Object - Class Win. Save the above script to a . OSDComputer. Name. Go to Software Library, Packages and create a new package. Give the Package a name, e.

OSDComputer. Name. Check This package contains source files and enter the location where you saved the script.

Remember that it has to be an UNC path. Click Next. 4. Choose Do not create a program and click Next. Click Next to confirm the settings. Click Close when the wizard is complete.

Distribute the Package to your DP’s. Using the script in a Task Sequence. Edit your OSD Task Sequence and add a New group after the Apply Drivers step. It’s important that you add the new group before the Apply Windows Settings and Apply Windows Network Settings steps. Name the new group like OSDComputer.

Name. 3. In the new group, create a new Run Command Line step and call it Set Power. Shell Execution Policy. Enter the following in the Command line field: powershell.

In the new group, create a new Run Command Line step and call it OSDComputer. Name. ps. 1. Enter the following in the Command line field: powershell. OSDComputer. Name. Check Package and select your newly create package OSDComputer. Name. In the new group, create a new Run Command Line step and call it Revert Power. Shell Execution Policy.

Enter the following in the Command line field: powershell. You should now have a new group with three steps. Make sure they’re arranged like below. That’s all! Run your Task Sequence on a lab client and check out the results. Principal Consultant and Enterprise Mobility MVP. Nickolaj has been in the IT industry for the past 1.

Calculate MD5 and SHA1 File Hashes Using Power. Shell. The majority of software distribution occurs electronically. However, the larger the downloads, the larger the risk of corrupted data transfer. Hence, it's very useful to be able to verify the integrity of downloaded files.

Cryptographic hashing algorithms provide one way to do this. A hashing algorithm takes a series of bytes (such as the bytes of a file), performs a calculation using those bytes, and produces an output value of a fixed size (e. The goal of these hashing algorithms is that no two inputs should produce the same output. Two common hashing algorithms are the Message Digest 5 Algorithm (MD5) and Secure Hash Algorithm- 1 (SHA1). These algorithms have been shown to contain flaws (i. Figure 1: An SHA1 hash value for an .

Figure 1 and Figure 2 show practical examples of hash values. Figure 1 shows an SHA1 hash value for an . Best Recording Software For Line 6 Ux2.

Microsoft Tech. Net. Figure 2 shows two MD5 hash values for Open. Office. org installers. If you download these files, you can calculate the SHA1 or MD5 hash values to verify whether the files downloaded without any data corruption. Figure 2: MD5 hash values for Open. Office. org installers Introducing Get- File.

Hash. ps. 1Microsoft doesn't provide a command to calculate hash values for files, so I decided to write a Windows Power. Shell script, Get- File. Hash. ps. 1, that calculates MD5 or SHA1 hash values for files using the Microsoft . NET Framework. The script requires Power. Shell 2. 0 or later. You can download it by going to www.

Instant. Doc ID text box, and clicking the 1. I recommend placing the Get- File. Hash. ps. 1 file in a directory in your path. To execute the script, follow the syntax. Get- File. Hash .

Wildcards are permitted. The script will accept pipeline input in place of the - Path parameter. If you want to specify the name of a file that contains characters that Power.

Shell normally interprets as escape characters (e. If you use - Literal. Path, you can’t use wildcards and the script will ignore pipeline input.

Note that the - Path and - Literal. Path parameters are mutually exclusive.

The - Hash. Type parameter's value must be the string MD5 or SHA1. If you omit - Hash. Type, MD5 is the default. Get- File. Hash. ps. MD5 or SHA1 hash value.

Figure 3 shows a sample command and its output. In this command, the filenames are being provided through pipeline input. Figure 3: Sample command and its output Understanding the Script. Get- File. Hash. ps. Power. Shell 2. 0 and later: Comment- based help and advanced function parameters. Comment- based help enables the Get- Help cmdlet to display help information for the script. Advanced function parameters allow the script to behave like a cmdlet.

Comment- based help is a series of comment lines (lines beginning with #) or a comment block (text enclosed between < # and #> ) that contains special keywords that Power. Shell uses to generate help information. If you use the command.

Get- Help Get- File. Hash. Power. Shell uses the special keywords (e. SYNOPSIS, . DESCRIPTION, . PARAMETER) to generate the help text. Comment- based help is a great addition to Power.

Shell 2. 0 that makes it very easy to self- comment functions and scripts. Run the command. Get- Help about. Get- File. Hash. ps.

Listing 1 shows the script's Cmdlet. Binding attribute and param statement. Cmdlet. Binding enables cmdlet- like behavior for the script's parameters and specifies the default parameter set. The param statement contains three parameters, which are declared with Parameter statements. Each Parameter statement includes attributes that establish the parameter’s behavior.

The attributes are as follows: Parameter. Set. Name=. If a parameter doesn’t specify a parameter set, it’s valid for any parameter set. The Parameter. Set.

Name property of the $PSCmdlet object contains the current parameter set name. Position=n: The parameter's position on the command line. Position=0 means the parameter must appear first, Position=1 means the parameter must appear second, and so forth. Mandatory=$TRUE: Specifies that the parameter is required.

If the parameter isn’t specified, Power. Shell will prompt for input for the parameter. Value. From. Pipeline=$TRUE: Specifies that the parameter's input can come from the pipeline. For more information about these attributes, run these commands at a Power.

Shell prompt: Get- Help about. The begin scriptblock executes once before the pipeline processing, and the process scriptblock executes once for each pipeline item. If there is no pipeline input, the begin and process scriptblocks each execute once. Inside the begin scriptblock, the script validates that the - Hash. Type parameter is either MD5 or SHA1 and creates the $Provider variable, which contains the .

NET cryptography object that computes file hashes. Next, the script determines whether the - Path parameter appears on the command line and whether it’s bound. If the - Path parameter is present but not bound, the script assumes the input will be coming from the pipeline and sets the $PIPELINEINPUT variable to true.

The begin scriptblock also contains the get- filehash. I’ll describe the get- filehash. Inside the process scriptblock, the script checks to see whether the Path parameter set is active (i. Path parameter was used).

If the Path parameter set is active, the script checks the $PIPELINEINPUT variable’s value to determine whether it should take input from the pipeline or from the content of the - Path parameter. If there is pipeline input, the script executes the get- filehash. If there is no pipeline input, the script uses the Get- Item and For. Each- Object cmdlets to send input to the get- filehash.

If the Path parameter set isn’t active (meaning Literal. Path is the active parameter set), the script uses the Get- Item cmdlet with its - Literal.

Path parameter to retrieve the file. If the Get- Item cmdlet succeeds (that is, the $file variable isn’t empty), the script passes the $file variable as a parameter to the get- filehash. The get- filehash. Function. As I mentioned previously, the get- filehash. Listing 2, is the workhorse function of the script. It performs three tasks: It validates whether the $file parameter’s value is really a file.

This is necessary because Power. Shell paths can refer to items other than files, such as registry subkeys and directories. It calculates the file's MD5 or SHA1 hash value. The function calls the cryptographic provider's Compute. Hash method, which calculates a hash value based on a stream of bytes (in this case, the contents of a file). This result is returned as a string of bytes, so the function uses the . NET String. Builder object to build a string containing these bytes as a hexadecimal string.

It outputs a custom object containing the file's full name and its hash value. The function uses the Select- Object cmdlet to output this custom object. File Hashing Made Easy. Get- File. Hash. ps.
