Another strange problem (running Samba 1.9.18p10 on AIX 4.3.1):

If I map two drives to two different shares of the same Samba server like:
      net use e: \\smbsrv\axs
      net use f: \\smbsrv\zrl-afs
and click on E:\ in the explorer - fine.

If I then click on F:\ in the explorer I get:
      F:\ is not accessible.
      The specified network resource or device is no longer available.
      Retry/Cancel
but after clicking either Retry or Cancel, I will see my files.

Same when I now click on E:\ again:
      E:\ is not accessible.
      The specified network resource or device is no longer available.
      Retry/Cancel
but after clicking either Retry or Cancel, I will see my files, all
      completely reproducible (from Win95 and NT4).

Any ideas?


Here some debug output, with debug level=4 I see in the log.smb:
 after clicking on F: in the above description
