Logical Tech

I recently was writing a script which required me to find the IP of the local machine and use it later on. I stoped for a minute and realized that some computers will have one network card and some will have 20, including virtual adapters. So I knew there had to be a way to figure out which network cards were being assigned an address and see a list of them. I came up with the following:

(gwmi -query "SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled=TRUE").IPAddress

Then, to reference any single NIC, if there are more than one, you only need to specify the one you need out of the array with [0] or [1] etc etc.

Not PERFECTLY simple, but practical and functional!

This script Checks a list of remote computers. You specify the servers inside of the $servers variable by placing each in quotes with a comma between entries as I have done below within the script. All you must do then is simply run the script. WMI will discover all drives on the remote machine and give you the total size, used space, free space and percent free. Entries below 15% will be shown in red and all others will be shown in yellow. You can add as many servers as you like, or easily mod the file to read from a text file.

You will probably want to save your credentials with this script as I posted about here for ease of use.

I use this particular script a lot.


#Retrieve Drive Space on Remote Computers

#SET TARGET SERVERS
$servers = "Server1", "Server2", "Server3"

$gb = 1024 * 1024 * 1024
foreach ($target in $servers){
write-host "Checking $target..."
$obj = (gwmi -query "select * from win32_logicaldisk where Size > 1" -computername $target -cred $pw)
foreach ($disk in $obj) {
$freespace = ($disk.freespace / $gb)
$totalspace = ($disk.Size / $gb)
$freepercent = (($freespace / $totalspace)*100)
if ($freepercent -lt "15") {
write-host "Drive" ($disk.deviceid) "has" ($disk.freespace / $gb).ToString("n") "GB Free of" ($disk.Size / $gb).ToString("n") "GB." $freepercent.ToString("n") "% Free." -foregroundcolor red
}
else {
write-host "Drive" ($disk.deviceid) "has" ($disk.freespace / $gb).ToString("n") "GB Free of" ($disk.Size / $gb).ToString("n") "GB." $freepercent.ToString("n") "% Free." -foregroundcolor green
}
}
}
