On my development I have SQL 6.5 and on above SQL 7.0 database which have been upgraded from 6.5. After completing the tests in 7.0 I've uninstalled the 7.0 version and tried to use the 6.5 server. Then I got the following error message :
Db-library network communications layer not loaded.
I am aware that the MS Server client allows to choose which of about 6 methods to communicate with the server and default would be TCP/IP or Named pipes. We use only Multi-protocol with encryption.
I've also checked its settings against other machines and protocols installed on the server.
Still I'm hanging with the same above problem.
Could anyone shed light on this issue to resolve.
