Auditing hardware and software for all machines in your domain can be time consuming. For small organizations, it may be a bit manageable provided that you already have a checklist of items that you need to look at for auditing purposes. CPU, disk, RAM, OS, service pack versions, etc. are just a few of those things you would like to take into account when doing auditing and inventory. For larger organizations, this could be a big challenge. Since I work for an organization that provides IT services for clients, we are required to maintain server information for auditing and inventory purposes. Imagine me doing this for almost 200+ Windows 2000 and Windows 2003 servers in multiple domains, not to mention Windows XP workstations. Being a lazy guy as I am, I wrote a script to simply automate this task. It uses VBScript and WMI to retrieve hardware, software and operating system information from computers in the domain. This requires administrative rights on the machine where this script is executed. It generates a text file (with filename servername_yyyymmdd_Audit.txt) which contains the information retrieved by the script. This is my list of information, you can always generate a lot more information by referring to the WMI SDK. Simply replace the value in the strComputer variable to the name/IP address of the computer you wish to audit

On Error Resume Next

Const HKEY_LOCAL_MACHINE = &H80000002

‘change this value to the IP address or hostname of the machine you need to audit
strIPvalue = “.”

WScript.Echo “Inventory Complete “

If you are dealing with an organization with more than 50 computers and servers, it would still be tiresome to manually execute this script on each machine/server. A better way to do it is to have an Excel spreadsheet that contains the machine names/IP addresses of all the computers in your domain. read through the list and generate the text files based on that list. In my next blog entry, I will start with reading an Excel spreadsheet using VBScript and continue on to incorporate this script.
