Logon Script which displays Server infon onto Desktop

Does anyone have a logon script which displays certain info on the desktop? I’ve seen one before that displays the following (Win 2k3 and Win 2k8 server)
-Server Name
-Domain Name
-Local Drives, how much space is free
-Last Reboot
-(other information I can’t think of)

Can anyone help me with writing this?
Thank!
