I looked at the wireshark trace in post #25 (by Alexey) and I see what looks like a server bug in this old version of Samba (Samba 3.0.25). Note that Samba 3.2.4 is current, and Samba 3.0.32 contains various highly recommended fixes (Released in August Samba 3.0.32 "is the latest bug fix release for Samba 3.0 and is the version recommended for all production Samba servers running this release series")
In frame 8 the client opens a file (imagehost.pl) which succeeds
In frame 10 the client requests information on the same file which succeeds
In frame 14 the client tries to set the file size on the same file and the server (incorrectly) returns "STATUS_OBJECT_PATH_NOT_FOUND" ... obviously that can't be correct because the server just gave the client info on the same file in the previous request and there is no delete in between.
