Network shares ... reboot with out restart PC

WD TV LIVE Plus keep losing my network shares and I have to reboot my PC for them to be seen again and it’s annoying me to reboot my PC when not needed to.

Any way I can restart the sharing of files on my PC cause I have unshared them and re-shared them again but that didn’t work.

Help would be grateful.
