Retrieve Dell Service Tag Remotely

Well today I had to connect to one of my client's servers and download the Dell Raid Storage Management tool for the machine to check something in the RAID config.  I couldn't remember the Dell model number nor retrieve the service tag.  In the end I used the PowerShell and WMI to retrieve the service tag:

in Windows PowerShell execute the following cmdlet:

get-wmiobject win32_bios

Amongst other BIOS info, the cmdlet returns the serial number.  The serial number Dell program into the BIOS is the system service tag :)

I could then go onto the Dell support site, enter the service tag and go straight to the relevant downloads for the server I was dealing with.
