Retrieving hdd volume sn in a 98 network enviroment

Hi all

So lets say i have a simple application that works through network and reads
"server" computer hdd volume serial number and depending on licence runs or
not ( files on "server" are simply shared) So if i have a configuration like
Win98 (aka client)<-> Win98 ( aka server ) , the client machine reads SN
through winapi functions GetVolumeInformation and GetFileInformationByHandle
and gets "servers" hdd volume serial number. Now the problem is that if
"server" is Windows98 it returns a 0 serial number ( if "server" is windows
xp or windows 2000 everyhing is ok) Is there a way how to solve it ?
