Half an idea is a good start, maybe we can help fill in a little of the gap.
In my opinion, if you are not committed to the Debian install, you may consider installing a more user friendly Linux environment based on Debian, such as Linux Mint (my favorite), or one of the Ubuntu variants (Ubuntu, Lubuntu, MATE, etc.). Forum support for all of these distros is great, and their forums are generally well laid out with folks willing to help. Father Debian can be quite daunting. When I first started using MC for linux I tried many of the Debian variants, and mounting my network share was done the same way in all.
When you install one of the other distros more than likely you will have a choice to install the new distro along side Debian, making a choice between them at boot, so you won't really lose anything.
All that being said, you may need to post more details to get help with the issue, such as what files you modified to enable the share, and what text strings you are using in those files.
