Re: Any help here???



I'm using ADO.NET - specific classes used were
1) System.Data.SqlClient - connection to Microsoft SQL Server - I also have
version 08.00.0384 of SQL Server 2000
2) System.Data.OleDb - connection to other Access Databases
3) System.Data.Odbc - used this likewise.
For discussion, like to simply stay with ADO.NET - System.Data.SqlClient.

Next, I apologize for discussion concerning MDAC - I was 100% sure how this
was used - but in past - system would advise me I needed latest during
debugging. I've also researched article from Microsoft saying when you
troubleshoot SQL Server connectivity issues - you should investigate the MDAC
version on the client, not on the server. Article was MDAC Technical Article
Pg 3 - Installation Versions and SQL Server Versions. I just thought it
might apply there.

Finally, since issue now is completely understood as ADO.NET - SQL provider,
I'd like to move to next issue. What could be causing no connects during
open operation?

Thanks always,
