VB Script to check disk space and email results

Here is a script I hacked together that checks disk space of your servers and emails it to an address. This can be scheduled using Windows Task Scheduler.

Requirements:
- CDONTS – http://kb.swsoft.com/en/560
- Needs to be run under administrative rights

‘ Sample code for monitoring windows disk space
‘
‘ This script reports the drive usage of all fixed drives on the systems
‘ specified. The report will be sent via plain text email to a specified
‘ recipient address (see last line in file).
‘
‘ This sample can be used in a production environment to set up an
‘ unattended disk utilization report system.

‘ Constants for drive types
Const Unknown = 0
Const Removable = 1
Const Fixed = 2
Const Remote = 3
Const CDROM = 4
Const RAMDisk = 5

‘ general constants – NEED TO BE MODIFIED FOR YOUR ENVIRONMENT
Const MailServer = “smtp.mydomain.com” ‘ Mail Server to use (SMTP)
Const MailServerPort = “25″ ‘ SMTP Port used at Mail server (25 is default)

Const LOCAL_HARD_DISK = 3

‘ Send a mail message
Sub SendMail(Sender, Recipient, Subject, Message)
Set objMessage = CreateObject(“CDO.Message”)
objMessage.Subject = Subject
objMessage.From = Sender
objMessage.To = Recipient
objMessage.TextBody = Message

objMessage.Configuration.Fields.Item _
(“http://schemas.microsoft.com/cdo/configuration/sendusing”) = 2

‘Name or IP of Remote SMTP Server
objMessage.Configuration.Fields.Item _
(“http://schemas.microsoft.com/cdo/configuration/smtpserver”) = MailServer

‘Server port (typically 25)
objMessage.Configuration.Fields.Item _
(“http://schemas.microsoft.com/cdo/configuration/smtpserverport”) = MailServerPort

objMessage.Configuration.Fields.Update

objMessage.Send
End Sub

   How can this accommodate a list of servers from a text file instead so it can read that file and work the list, instead of copying and pasting the same commands for every server?

   Understand that for 3 or 4 servers it might be sufficient, but when they get in the dozens or hundreds or systems, it will be a long script.

   You can’t be serious…

   As per Hap Cluff comments, I work in an environment containing over 200 servers that include additions and decomms constantly, this script is seriously lacking…
