Then i log in to my userone's file from start---run---\192.168.1.250userone
on giving this command the server prompts for a username & pass, It accepts the username & pass and I can view/edit userone's files.
so you are logging on as userone into your server..
Now simultaneously I want to open usertwo's files so i type from start---run--\192.168.1.250usertwo
Immediately it gives me an error that you might not have the permissions to access the resource.
you can't.. you say to your server you are userone.. userone can't see usertwo home dir.. and this is not a SME limitation, is a feature..
After that I right click on network neighbourhood and disconnect the network drive formed by connecting to userone & then re-try to login to usertwo this time it logs in perfectly.
because now your server recognize you as usertwo.. if you try to access userone's files, you can't..
Now the question is what stops me from logging in the second user simultaneously. how can it be achieved?
you can't (normally) have access to another user home directory.
if you need some files/dir to be shared between more than one user, you should use ibays
I tried doing the same on a ready made NAS box with single hardrive, with 5 users and folders, I could easily log in all users with their usernames & passwords simultaneously.
well.. you don't say anything about that nas, so we don't know anything about it and the way it works.. btw, SME and all linux distro (and windows too) work as you are experiencing..
Ciao
