Job ID: 32083762

Budget: $30 – $250 USD

Hi. I need to scan a few windows environment networks for: hostname, hardware specs, installed software etc.
A few important requirements:
1. These are standalone computers, they are not connected by a domain or a workgroup.
2. Most computers have the same local admin name and password.
3. I am looking for an open source tool, I already know there are many expensive solutions for this.
