[Samba] Mounting DOSBOX on a remote share

[czezz]

It is probably not strictly related to SAMBA itself but let me try to ask you for advice.
Using smbmount I have mounted one of smb/cifs share to /root/test.
This share has RW access and no authentication is required.
Now, under DOSBox, whenever I try to mount /root/test I get this error
(command sent under DOSBox: mount c /root/test).
 Directory /root/test doesn't exist.
Any other directories, which are not smb/cifs I can easly mount.
Moreover: I have tried to do this same operation under WinXP and it just works.
Does anyone know how to fix it or what is wrong ?
Best regards,
