MsSQL server 6,5 and Delphi4

We do have microsoft backoffice small business pack with mssql server ( 25
licenses )
When trying to access mssql server via an application built with delphi4 we
experience a
problem after opening 17 tables.
We did believe that the 25 licens referred to how many workstation could be
connected but
it seems that whenever a table is opened it counts like one user connected.
Appreciate any advice to come around this.

thanks on beforehand
