Hello everyone - new here, and looking for some knowledge.  Let me start by explaining what I want to do - there may be multiple ways, or no way at all to acheive this.

I have a database I have created.  I have people who would like to use it.  I do not own/or want to own there data/server.  What I would like to be able to do is shut them out from using the layout/database if issues arise.  Possibly make the layout authenticate monthly?  The issue lays in the fact that I will not own or control their network or server.  Help please?!?!?!

will domain control work?
