Thanks muungwana for your reply and sorry it's taken me a few days (got called out of town)

Well since then I have taken a 'side by side' look at my smb.conf files and ex the bad machine located discrepancy
way down amongst routing so copied the 'good' file across changed a couple of entries re machine names etc and
viola the "Invalid command: net rap share list" whatever that was has disappeared -

However - though not a big problem but still weird is an error I now get while trying to mount a couple of shared folders.
retrying with upper case share name
mount error(6) : No such device or address
Refer to the mount.cifs(

manual page (e.g. man mount.cifs)
I have deleted the share points - remade the shared points with same error?
I have 3 shared folders on that machine - 2 giving problems are folders within my home and the 3rd which is on a storage partition works fine?
I have tried creating other folders within my home and setting them to share with same error?
However - creating another shared folder within the storage partition works just fine?
If you can suggest a reason for this taking place I would be interested to have your input.
Again - thanks for response.
