2 GB barrier in DOS

I am currently experiencing a problem with a DOS based workstation
trying to access an 8GB partition on a LAN.

I have found that the problem lies with DOS being an 8bit OS and only
capable of accesing a MAX of 2GB. When I try to access the partition,
DOS falsely reports "0 bytes free." I know the problem lies in the FAT
staructure, and I know that there is software that can "work around"
this limitation.

It does so by falsely reporting free space just under 2GB (when
freespace > 2GB). This allows applications to write to the partition.
When the actual free space is under 2GB, then the freespace is reported
accurately.

Does anybody know of a fix?
(I'm currently using a DOS/WFW workstation accessing a LAN Server 4.0
server running on a Tricord ES-4000 Super Server.)
TIA,

Steve
