SMB failure after upgrade

I’ve seen a few posts about this but no resolution.

I upgraded from 14 to 17.1. Now kodi cannot see the SMB shares I have on the network. The computer does fine (from the O/S).

\\mediacenter\myvids exists and I can browse it fine

smb://mediacenter/myvids does not work inside kodi.

Any ideas? This was all fine before I upgraded.
