I had the same problem after upgrading to Ubuntu 17.10. Suddenly, my CIFS shares would no longer mount. Adding vers=1.0 to the mount options fixed it for me. Admittedly, this is a bit of a bodge, but some network share access is better than no network share access.
My /etc/fstab file previously had the following 4 lines at the bottom:
# Network File Shares
//phc.imsu.ox.ac.uk/phc /mnt/PHC cifs credentials=/home/benjamin/.smbcredentials,iocharset=utf8,sec=ntlm,dir_mode=0777,file_mode=0777 0 0
//phc.imsu.ox.ac.uk/departments /mnt/DEPARTMENTS cifs credentials=/home/benjamin/.smbcredentials,iocharset=utf8,sec=ntlm,dir_mode=0777,file_mode=0777 0 0
//femur.imsu.ox.ac.uk/phc_cprd /mnt/PHC_CPRD cifs credentials=/home/benjamin/.smbcredentials,iocharset=utf8,sec=ntlm,dir_mode=0777,file_mode=0777 0 0
Changing them to:
# Network File Shares
//phc.imsu.ox.ac.uk/phc /mnt/PHC cifs credentials=/home/benjamin/.smbcredentials,iocharset=utf8,sec=ntlm,dir_mode=0777,file_mode=0777,vers=1.0 0 0
//phc.imsu.ox.ac.uk/departments /mnt/DEPARTMENTS cifs credentials=/home/benjamin/.smbcredentials,iocharset=utf8,sec=ntlm,dir_mode=0777,file_mode=0777,vers=1.0 0 0
//femur.imsu.ox.ac.uk/phc_cprd /mnt/PHC_CPRD cifs credentials=/home/benjamin/.smbcredentials,iocharset=utf8,sec=ntlm,dir_mode=0777,file_mode=0777,vers=1.0 0 0
Resolved the issue.

Hamachi version 2.1.0.174 doesn't work because it's not compatible with the newer glibc version 2.26, which is included in Ubuntu 17.10. The hamachi daemon will crash the moment you try to login with the following error:
See this forum post for more details
I'm affraid the only way to solve this is to wait or push for LogMeIn to release a new Hamachi version that is compatible with glibc 2.26.
UPDATE 18th January 2018: LogMeIn has released Hamachi for Linux beta version 2.1.0.189. This version is compatible with glibc 2.26 and can now be downloaded from https://www.vpn.net/linux
