I build aspx apps at work. A small business has asked me to build them an internal web app for them. They own a box running server 2005 and are using it as file server the best I can tell. This server should do the trick to host an app to be accessed by a handful of employees. My question is - generally speaking, can I just install IIS and the express edition of Sql Server to store their data without the company having to buy extra packages and licensing?
Again this is just a general question, not expecting a fully qualified answer... Simply, is it generally legal for the business to implement this software considering they already own the server?
(this may be more appropriate in the /bytes/it/windows section - sorry if that's the case)
