Subject: Informix as a linked server in SQL Server
Has anybody managed to get this operational? I'd really appreciate any advice, but I realise this is a long-shot.
I suspect I've got a microsoft issue, but when I install the client SDK, the Microsoft Server cannot initialise the connection.
I've been following this guide, but get errors on the final step
