samba - Dec 2002 - Error code -43 when copying from OS X to Samba server

Hi all.

Here's my situation with this error.

I'm running Mac OS X 10.2. I connect to two servers: one running 
Win2000 Server (sp3), the other running Linux with Samba 2.2.6. The 
shared volume on the Linux box is an ext3 volume. I'm connecting to 
both of them using DAVE v4. I can copy files to the Win2000 server just 
fine. Most of the time everything works great with the Samba server. 
But every now and then I'll have files that I can't copy to the Samba 
server. It gives me the "The operation cannot be completed because one 
or more required items cannot be found. (Error code -43)" message. It's
not very often. Right now I have a few JPG files on the Win2000 server. 
These files were created with Photoshop just by using the "Save..." 
command. I can copy them to my Mac's HFS+ hard drive and back to the 
Win2000 machine. But when I try to copy them from either source to the 
Samba machine, I get the error. Here's the interesting part. If I open 
them back up in Photoshop and save them as JPGs using the "Save for 
Web..." command, I have no trouble coping the new files to the Samba 
server. It seems to me that it has something to do with the resource 
forks.

Anybody have any ideas about what the problem is?

Thanks a lot.
