Copy windows files to samba

OK I'll start off by admitting that I am no Linux guru so bear with me. We have multiple Redhat Linux boxes at our various sites that operate solely as file servers. I'm having an issue on one of these servers however. I have samba installed and setup with shares however I cannot copy any files from Windows to the share. When I try, most of the time I get a message indicating that the file length is too long and I basically need to change it to 8 characters or less.

Any ideas? I don't have this issue on any other of our servers and as far as I can tell the configs are the same.

 

Oh and the error I get is "the destination does not support long file names" so it may just be a Windows thing...
