PowerShell – retrieve inventory for your servers

Every system administrator needs from time to time get info on his servers for many reasons such as to keep up network and system documentatyion up to date. Here is another handy PowerShell script that will get complete server info.
Script is simple and easy to use. Just add your server names in the Servers.txt text file and save it under your root c:> drive and run the PowerShell script.

erroractionpreference = "SilentlyContinue"

$a = New-Object -comobject Excel.Application
$a.visible = $True 

$b = $a.Workbooks.Add()
$c = $b.Worksheets.Item(1)

$c.Cells.Item(1,1) = "Organization"
$c.Cells.Item(1,2) = "Server Name"
$c.Cells.Item(1,3) = "Operating System"
#$c.Cells.Item(1,4) = "IP Address"
$c.Cells.Item(1,4) = "Service Packs"
$c.Cells.Item(1,5) = "System Type"

$c.Cells.Item(1,14) = "Report Time Stamp"

$d = $c.UsedRange
$d.Interior.ColorIndex = 19
$d.Font.ColorIndex = 11
$d.Font.Bold = $True
