samba - Mar 2007 - Network name no longer available error on large file write to FAT Shares

Hi ,

I am sharing my FAT Shares over samba.

When i copy small files (less than 100MB ) everything is fine.

But when i copy large files( >200MB) my windows machine is getting
busy for some time and i am getting error "Network name no longer
available"
but the file is
getting copied properly.


Regards
Kumar
