SMB 2GB limit

Hello all- My company has a heterogeneous Video Production environment. We have a Leopard Server/Promise RAID/Xsan. We have FCP files larger than 2GB... We are attempting to share these files to Windows XP clients that are connecting to the Xserve via. SMB. Although they can connect to the Xserve, they are prohibited file exchange with these files due to the SMB 2GB file size limit. Is there an answer to this problem? Could I eliminate this problem by opening NFS from the Xserve, install NFS clients onto the Windows stations, then connect to the share over NFS?? Please let me know your thoughts and experiences... Thanks to all who contribute!!
