[Samba] Invalid listing, samba 3.6.6

[Traugott Simon]

Hello list,
i do have a problem with Amanda and Smbclient again.

Im trying to backup some shares and I do get some errors which i cannot fix:
 
 ? smbclient: Error reading file \Dtel\El\2009-11 u TEST\2009-11\Logos\meeting, England\P1020272.MOV : NT_STATUS_OK
  ? smbclient: Didn't get entire file. size=86525282, nread=61719840
  ? smbclient: NT_STATUS_OK opening remote file \Dr\P1020273.JPG (\Dnd\File)
  ? smbclient: NT_STATUS_CONNECTION_INVALID listing \Drittmittel\Directory\*


I have no idea how to solve this.
Im using Samba 3.6.6 with Debian Wheezy, the share is on a Windows Server 2008 R2.

Please help if you can.

Thanks!
