Maybe it helps to add some samba options for Mac
See also Configure Samba to Work Better with Mac OS X - SambaWiki
Does it work with IP like \\192.168.0.1\share
or name like \\nsdc-mysrv\share
?
Are there dots in the usernames? Does it work with a username without a dot?
Which Windows version are you using? Did you try another Windows client?
A Windows client could get confused when connecting to the same share with different users so tests won’t work anymore.
