[Firebird-net-provider] Interbase 4.0 Compatiblity

Hi,

My development machine is Win XP, Firebird 1.03, .net 1.1, FBNetProv
1.1.  The production box is Win 2k Server, Interbase 4.0 (sic), .net
1.1, FBNetProv 1.1.  The ASP.NET project works great on the development
box.

But when I try to run it on production (IB 4.0), I get

GDSException: Exception of type FirebirdSql.Data.INGDS.GDSException was
thrown
...
FbException: connection rejected by remote interface

trying to open an FbConnection.  The connect string is

    public connStr As String = "User=xxx; Password=xxx;" & _
      "Database=C:\\db\\xxx.gdb;" & _
 
"Server=localhost;Port=3050;Dialect=1;Charset=NONE;Role=;Connection" & _
      "lifetime=15;Pooling=true;Packet Size=8192"

I can connect to IB 4.0 db's via ISAPI DLL's using http on the same web
site.

Does firebird-net-provider work with IB 4.0?  If not, any suggestions
what I might try to connect to the db via asp.net?  Unfortunately,
upgrading from IB 4.0 is not an option.

Thanks,

Andy
