>>>For tcp/ip, at least for Oracle, SQL*Net is required on the client and the server. Do you know if this is true for SQL server, or if some equivalent is necessary? There is usually a "listener" on the server side, and the client side has software to install as well.

If is installed the odbc drivers of SqlServer in the Client, try run
"Client configuration utility" (This program is in CD Sqlserver\I386\ODBC) then select
1)Net library option:Tcp/ip Sockets
2)Advanced:Server: MyServer
:dllname: Tcp/ip Sockets
:connection string: 999.999.999.999,(1433)

This work for me
