MS office files alone do not open from network in Samba share/kubuntu 14.04 LTS system

I am new to Linux-kubuntu 14.04 LTS. I successfully created a live USB for 12.04, installed it, used as a stand alone laptop for a fewdays and then updated to 14.04 LTS. Had some issues with default e mail and browser but after changing them and with few attempts everything started working-nicely.

I don't rememebr whether samba was preinstalled or not, as i have autoremoved many times and also reinstalled it.

The first peculiarity i have noticed is, even if I auto remove samba and almost all connected packages to my knowledge, I am still able to see sambashare under Dolphin.

Now, and also many times in between, I am able to see all windows computers in my laptop, but kubuntu laptop is not appearing in any other computer.

Not even once, I have been able to open MS office files though Libre office acts as if it is opening the clicked document, but then nothing more happens! However I have able to copy, paste the files into my computer and work on them! And also PDF, photos etc open with no issue!

During my many of the experimental times, it used to ask for a password, but even if enter my login password it used to ask again and again.

Though samba is shown not as installed under Muon discover, even now samba share appears under dolphin as above.

Though relavant or not here, i give the output of smbtree command here; Followed by testparm command:
SMBTREE:
