    Use this topic to post useful scripts for others, in PowerShell, VBS, .bat, PHP ... whatever has worked well for you in making IT administration easier for you! Please be sure to include information about how to run the script, if special command-line parameters are needed, etc.

    Windows PowerShell 2.0: I have learned PowerShell on the fly this year in times of absolute need. I wanted to post some of the resources that I have found.

    I have used PowerShell mainly for tasks with user folders;  comparing home folders to Active Users, for example (to determine if home folders are missing, or conversely, to know which home folders belong to inactive students and should be deleted).

    Here is a script which I use every day. We have a current issue where something in Windows 7 is deleting students' home folders on login. I run this script every hour or two and it tells me which of the students no longer have home folders on the server. I then restore their home folder manually with Previous Versions (Volume Shadow Services) and re-set security on their folder. Prior to this script, I was comparing entire lists of classes to the home folder share to see what was missing.

    This script relies on the ActiveDirectory module, and I have pre-mapped the student home folder share to a mapped drive (S:). I have highlighted the areas which are specific to my environment. I keep this script in a folder on my Win 7 workstation and I run it from within PowerShell ISE.

    Import-Module ActiveDirectory
    #list students who don't have home folders

    $timestamp = Get-Date

    # 1. get users from AD Students container, loop through them
    $theUsers = Get-ADUser -Filter {(Enabled -eq "True")} -SearchBase "OU=StudentAccounts,OU=Students,OU=Accounts,DC=alton,DC=school,DC=com"
    write-host $timestamp $theUsers.count enabled users found
    $folders = Get-ChildItem S:\

    # 2. for each user, does the home folder exist?
    foreach ($user in $theUsers)
    {
        #write-host $user.Name , $user.sAMAccountName
        $userHome = $user.sAMAccountName
        #does the home folder exist?
        $userFolderExists = Test-Path S:\$userHome
        if ($userFolderExists -eq "True") {
            #skip
        } else {
            write-host No home folder for user $userHome , $user.Name -fore darkblue
        }
           
    }

    In honor of the end of daylight savings for this year, I want to post this PowerShell command which I used to quickly check the time of my servers without having to remote into them:

    Get-WmiObject Win32_LocalTime -computerName SERVERNAME | Select-Object -expandProperty Hour

    if you type just this command, you'll see the different outputs available - I cared only about the hour today:

    Get-WmiObject Win32_LocalTime -computerName ALTONTS5

    I use this script in Windows to log all logins in my environment. It is applied as a login script for all users. A hidden share needs to be set up on a server with write access by everyone. My share has sharing permissions set to Full Control by Everyone, then NTFS permissions set to Modify for Authenticated Users.

    The output of the script looks like this (one line per login):

    Logon ; 8/23/2009 12:20:38 PM ; COMPUTERNAME ; USERNAME ;

    The script:

    ' Logs.vbs
    ' VBScript Logon script.
    ' This program demonstrates how to log information to a log file.

    I updated this script to read in a .csv file with a list of servers - so I can query the time of all servers in one script. The .csv file should be in the format (I'm including the first 3 lines of my file):
    Type,Name,Virtual
    Server,TTC,Y
    Server,ACSMAIL1,Y

    The updated script is
    #This script runs against a list of servers in a CSV file, which should have the columns Type,Name,Virtual
    #It checks the time (hour only) of the server
    $CSVPath = "C:\Users\pmcleod\Documents\Scripts\Servers.csv"
    $TheServers = Import-Csv -Path $CSVPath | Sort-Object -Property Virtual,Type,Name

    forEach ($Svr in $TheServers)
    {
        $Svr.Name
        Get-WmiObject Win32_LocalTime -computerName $Svr.name | Select-Object -expandProperty Hour | Format-Table -Property $Svr.Name, Hour   
    }
