I have a complex data entry application written in Access VBA using
DAO (not MSDE) and located on a Windows 2000 Advanced server.

I want to make the application available to 2 to 5 simultaneous remote users. 

I've looked at Citrix, but the cost is out of our budget. Remote
Administrator, Real VNC and PC Anywhere apparently can't restrict
access to a single application nor enable multiple simultaneous users
on the same machine.

Let's chat if you can find a remote access program that meets these
three criteria 1) simultaneous users 2)restrict access to a single
Access DAO (not MSDE) application and 3) <US$250.
