[Samba] I finde the files but I cannot open them!

[Tarjei Huse]

Hi, I just upgraded my one of my servers to 3.0.7 using the rpms for
suse 8.2.

now, hell has broken loose. The clients may log on, open shares, browse
folders, but they cannot open files!

Using smbclient I see that samba starts the transfer, than aborts. 

In my log I find a whole bunch of errors saying:
Sep 14 11:24:39 mail2 smbd[4464]: [2004/09/14 11:24:39, 0]
lib/util_sock.c:read_socket_data(384)
Sep 14 11:24:39 mail2 smbd[4464]:   read_socket_data: recv failure for
4. Error = Connection reset by peer

Does anyone know what may be wrong?

yours,
Tarjei
