We have got it to work using Edubuntu 11.04 which comes with LTSP. Just wanted to share details so anybody facing similar issues can benefit from our learnings. After installation of Edubuntu 11.04 on server we did make changes to configuration file as per details in my prev. mail (can be found below). In client machines while adding new connection thr' Winbee connection manager window, we had to enable 'DHCP' which was available on tab called 'update' and enter server IP there. That's it and it all worked like a charm. Thanks for your support and comments. Now we have one small issue. and trying to see if anybody knows solution for it. We have one server and 10 thin clients, for each client machine we created user as user1,user2 and so on. All these users show up at log-in screen in client machines from where you can click on user enter password and it will let you log-in. Is there anyway to restrict login to show only one user per computer?

When I tried installing Edubuntu 11.04 it took lot of time without success. Server already have Windows 2003 , Red Hat and while installing Edubuntu, (had to use manual partitioning as earier EDubuntu 10.04 was there) it got stuck at step where it kept saying "removing conflicting files ...." and was at that for 40-45 mins. I had to reboot and installed 10.04 then. Does Ebubuntu 11.04 takes this long for installation and partitioning? Did I miss anything?
