Make this hta script into web based solution along with additional queries. The web based solution would require a user at a client workstation/pc (without elevated permissions) access a URL which will query the client machine for information (i.e. OS version, browser information, proxy information, software installed, etc.). I was thinking of using WMI or similar for this but I'm open to ideas. Will provide what needs to be queried but for now, its windows machine. Should be able to access the URL from any browser (IE, Firefox/Chrome) and output into database.
For your information: the web server also runs on coldfusion/asp.
