[jcifs] SmbException by copying a File

[kku at shd.de]

Hi,

I try to copy a File (Zip-File) from an SMB share on a Windows 2003 
Server (SP1) to an other 2003 Server.
Sometimes it works great, but often the transmission crashes with an 
Exception:

jcifs.smb.SmbException:
jcifs.util.transport.TransportException: Transport1 timedout waiting for 
respons
e to 
SmbComReadAndX[command=SMB_COM_READ_ANDX,received=false,errorCode=The opera

       at jcifs.smb.SmbFileInputStream.read(SmbFileInputStream.java:152)

The connection between the 2 Servers is available at all the time and 
doesn't break.
Copying the File whit the Windows-Explorer or other tools works whitout 
problems.

What can I do?

thanks
