[PROBLEM] Samba mount seems to work but fails

[quattr0]

The symptom suggests a server issue for example permissions, Samba config, etc.

OK, thanks Tim.  I'll take a deeper look.  FWIW, i used the command line  you gave in the original post and change the version to 3 like below and am able to mount ./test

 sudo mount -t cifs //192.168.x.x/Music -o username=guest,password='',rsize=61440,wsize=65536,iocharset=utf8,vers=3.0,ro,dir_mode=0777,file_mode=0777 ./test
