I'm curious why you want to use a vbscript instead of following the
standard way of doing it as outlined here:

http://nagios.sourceforge.net/docs/3_0/monitoring-windows.html

Have you read the nagios documentation?  Here are a couple of service
definitons for disk checks from our working configuration

define service{
        use                             nt-server-check-disk
        host_name                       SCGVLMONITOR1
        service_description             Disk - C
        check_command                   check_nt_disk!c!95!98
        }

define service{
        use                             nt-server-check-disk
        host_name                       SCGVLMONITOR1
        service_description             Disk - D
        check_command                   check_nt_disk!d!95!98
        }

And here is the definition of check_nt_disk

# 'check_nt_disk' command definition
define command{
        command_name    check_nt_disk
        command_line    $USER1$/check_nt -H $HOSTADDRESS$ -p 1248 -v
USEDDISKSPACE -l $ARG1$ -w $ARG2$ -c $ARG3$
        }

ARG2 and ARG3 set the warning and critical levels. Hope this helps.
