samba - Feb 2004 - Network errors when coping files to a samba share

Hey group I'm having issues with my Samba shares, I'm able to map to the
home shares just fine I'm also able to create new files and folders and 
copy files from the desktop to the share. But when I copy files from the 
Home shares to the desktop I get Specified Network Device is no longer 
available. Any ideas? I'm running Samba 3.0.1 on Solaris 8 connecting to 
Windows 2003 AD. Enclosed in my conf files.
