I am mounting as the root user because I have not given my user permission 
to mount this share.

Following is the results of the troubleshooting steps that you gave me. 
I did not understand what would be wrong from looking at the strace.


---------------------------------------------
# mount -t cifs -o credentials=/etc/.smbpasswd //192.168.0.2/share 
/mnt/share
mount: wrong fs type, bad option, bad superblock on //192.168.0.2/share,
        missing codepage or other error
        In some cases useful info is found in syslog - try
        dmesg | tail  or so

# echo $?
32

---------------------------------------------

//192.168.0.2/share /mnt/share
