[Ilugc] could not update .ICEauthorityy

[gupta.chandan1 at gmail.com]

Hi,
Yesterday I changed the log-in settings.. from ask password while log-in to
dont ask password.
the next time i re-boot my system got this error

error1. could not update ICEauthority file /home/user/.ICEauthority

after closing that pop up I got next error pop-up

error2: There is a  problem with the configuration server.
(/usr/lib/libconfg2-4/gconf-
sanity-check2 exited with status 256)

error3: Nautilus could not create the following required folders:
/home/user/Desktop/,/home/user/.nautilus

thought of searching the solutin in ubuntu-forums thread.. got some thread..
one of which i followed and deleted the .ICEauthority file :( :(
should not have deleted that coz I got another solution like chmod stuff for
it. but pathetically theh ICEauthority is deleted.
Now what can be done?

please suggest...
