Working with Scheduled Tasks

So I've been getting the IT "general purpose" server up and running. I have all of my management tools installed, and now it's time to automate some reporting and maintenance functions. Right now, I have 3 scheduled tasks:

• Windows Service Monitor: This Powershell script looks at many of my servers and the services that I deem "important". It emails me if it finds any that aren't running. It's a terrible script; I pretty much did a Get-WMIObject query, ran some logic with a where-object statement and then dumped it out to a file. The beast is 900 lines long or something ridiculous (done through copying and pasting, not by hand). I KNOW that there's a more elegant way to do it, but I haven't got the time to spend on it. It does what it needs to do.
• Website Monitor: This script downloads the html code from a couple of web pages, then runs select-string to return a true or false based on whether certain text appears in the code. If the expected code isn't there, the script emails the admins, because something's not right.
• The "Start Patching" script: We run this script before we start patching to turn off our monitoring software. First, it disables our SNMP monitoring software, then it stopd the Spiceworks service to take spiceworks offline. We don't want a bunch of emails that so-and-so system is down. The last thing it does is to disable the above two scheduled tasks, and let me tell you that this took me a bit to figure out. Yeah, you use powershell, but you use it to call a CLI program called schtasks.exe, which I think is pretty weird for Windows Server 2008 R2. You'd think they'd have some powershell commands for the Tasl Scheduler, but no. So here's the syntax for disabling a script:

 $CommandDisable = 'schtasks.exe /Change /S ComputerName /TN "Windows Service Monitor" /Disable'
Invoke-Command $CommandDisable

So first, I put the command into a string variable. Using single quotes forces Powershell to interpret the double quotation marks literally (as part of the string itself). Then I can use Invoke-Command to run the string as a command. Schtasks.exe has a ton of syntax options. Way back when I remember using it to set up scheduled tasks from scratch from a batch file; it's got really great functionality (too bad it hasn't been ported to powershell (grumble grumble). Every Windows computer has schtasks.exe, so if you're curious pop into a cmd shell and type schtasks /?. The help function is layered, so you can type schtasks /Change /? and get help specific to the subset of the command structure. Fun stuff.
