Quickbooks Remote access

There are many answers to this question mostly depending on where the Quickbooks Database resides and the computer network being used. 

The easiest way is to log into your desktop from the remote workstation using tools like "Logmein" or "GoToMyPC".  These allow you to log into your PC that has Quickbooks installed and to control it as though you are sitting in front of it.  This can be done from any internet connected PC, and it is encrypted.  You should be able to google either of the above solutions to get you started.

If you have a windows server you may look into "Terminal Server" which is a bit more complex but is another solution.
