chown -R root directory_name

If you changed the group ownership also make that
chown -R root:root directory_name

1) Just to make sure, you are root when doing this?

2) What is the output of
ls -l /bin/su

1). how can i be root without doing su ?, i can only enter the root password when xwindow prompts
2) the output of ls -l /bin/su is

-rwxrwxrwx 1 glacier1985 root 104622 May 4 12:25 /bin/su

maybe you forgot your password ?
just log in as root and chown -R root /bin && chown -R root /etc

if you really forgot your root password ( i dont know why someone would forgot their password )
this might help : http://www.desktop-linux.net/root-password.htmRoot Password Recovery Guide
