[Samba] filename_convert_internal: checkname failed NT_STATUS_INVALID_PARAMETER

Dear All

I have a PCBSD machine with /media shared using samba.

Any microsoft clients can successfully connect to /media and browse directories I have created there.

When I plug in a usb device, I mount it into /media  eg: one labelled "PENDRIVE" becomes /media/PENDRIVE

Some clients can successfully read /media/PENDRIVE, others cannot. Although the clients that cannot view the directory, can successfully copy a file from there using the complete filename eg: if mapped as the U: drive on a microsoft win7 client I can copy u:\pendrive\claim.pdf from there

I looked at the logs under /var/log/samba, specifically log.hostname and noticed that for the client that fails there is

included below are excerpts from the log.hostname from both clients doing "dir u:\pendrive"


thanks in advance
