With at least telling wath the 'catastrofic failure' is I don't think we can help you! Do you get a message indicating something? – Birger Dec 13 '13 at 08:40

Delphi 2007 DCOM datasnap works with Windows 7 and Windows 2008(R2). But what Windows version are you using? Home or Pro/Enterprise/Ultimate? The Home version has several network features "neutered". – Mad Hatter Dec 16 '13 at 11:29

If you try to run DCOM datasnap without knowing how DCOM works and how to configure it, you're heading into a lot of trobles. You have to run dcomcnfg.exe and configure your server (and some dcom global settings). Also, when using COM based libraries like ADO you have to know how to setup the hosting application properly. DCOM is a powerful but complex beast.
