Well, nSanto17, dotobi and 58sniper thanks for your replys.
Now. Lets say I can work with XPHome using the .bat file to connect, we can live with that meanwhile we upgrade to vista business (and reload our PCs).
BUT, does SQL Server 2005 Workgroup (included in SBS R2 Premium) can be accesed by this XPHome machines running a .Net application?
Thanks again.
Jose Carlos
