While consolidating a variety of disparate domain names for a corporate client, it was useful to have a way to automatically get WHOIS information for all the domains. Two free solutions I found were:

1. MultiLook - Windows based utility that can find WHOIS info for domains and then export the info to HTML
1. Great for a one time lookup of domains. The interface is not perfect, but it does get the job done for most domains.
2. 4/5 stars
2. PHPWhois
1. Ideal for automated solutions and can easily be installed on XAMPP for Windows or other PHP/Apache based servers. A bit overkill for one time use.
2. 4/5 stars

If you are in a similar solution I hope this helps!
