Powershell script to get server specifications

Here is the usefull script that will get you server specifications like Server FQDN, Physical or Virtual info, Model, Total Memory, Bios Version, IP and MAC addresses, Subnet mask, Default Gateway, DHCP status, OS type, Service Pack, Serial Number etc.

Create a servers.txt file with the list of servers for which you want to get the server specifications. One server per line.

C:\temp\serverslist.txt

serverslist.txt example:

hostname
hostname2
hostname3

Now create a new text file and rename it to serverlist.ps1

Save the script to the same folder at C:\temp.

Before you’ll be able to run the script you will have to enable execution policy on your system (if you haven’t already):

Start the Powershell in elevated mode (Run as Administrator) and run the following command:

Set-ExecutionPolicy RemoteSigned

Now run the Powershell script by using this command:

powershell -noexit “& “”C:\temp\serverlist.ps1″””

server specifications

You should get server specifications results on your screen.
