Question

We have a server located at our office & we have 6 employees distributed over 6 different cities.
We are facing a case where these 6 employees sometimes try to login into the server through internet
concurrently and perform different tasks like ( opening our ERP system, checking
some emails, deleting some files) without disturbing each other i.e. each employee will
work independently from each other.

Of course, we would prefer a software which provides these features over the internet to pass all the firewalls or any obstacles.

I have found some applications like TeamViewer but only allows one user to have full control

What is OS running on your server. Assuming you have windows server you can use Remote Desktop Sessions – http://msdn.microsoft.com/en-us/library/aa383052(v=VS.85).aspx
