problem in user creation
 

hi all!
i have created users using
useradd -d /home/students/2001/cs101 -p ''
the directory cs101 was already there for some other user that has been deleted.
now after creating this user whwn i tried to log in
kde is unable to start.
it shows some pop up error messages like.........
--check that dcopserver program is running.
--no write access to $home(/home/2001/cs101)
however there is no problem in logging in to root.
pl help.

Thats probably the problem. The new user doesn't have ownership of the directory /home/students/2001/cs101. You can do this as root to fix:

chown <user>:<user> /home/students/2001/cs101

Shouldn't that be
chown -R $USER:$GROUP /home/students/2001/cs101
Or perhaps it would be better to delete the old students files and start with defaults?
rm -rf /home/students/2001/cs101
