Could Not Connect To Sql Server Dbnetlib

SQL 2005.  I upgrade to VS 2008 but didn't deploy because there were no changes requested.  I got a request dbnetlib connectionopen (preloginhandshake()). general network error last week and made the changes.

Depending on the version of ADO you might get passwords stripped out.

The application was using the connection string as "Provider=sqloledb;Data Source=myserver\instance1,1433;Network=DBMSSOCN;Initial Catalog=mydb;Integrated Security=SSPI;" I was able to connect to the SQL SERVER from SSMS, however when connecting from an application it was throwing http://www.sqlservercentral.com/blogs/whatilearntatwork/2012/01/16/sql-server-connectivity-error-sql-server-does-not-exist-or-access-denied/ the error [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied This is very generic one and can happen due to many reasons like (1) Account may not have access or password might be wrong (2) Connection might be blocked by a firewall (3) Since it is a named instance, the port might be different. In some cases it might be dynamic also, for which the SQL Server Browser service should be up and running. Looking at the connection string, everything looked good except for the "Network". I had no idea of what it is. Googling led me to this KB article from Microsoft which clearly explains what it is. Basically when an application is trying to connect to SQL SERVER, if one protocol fails then it tries to connect with another protocol. Example, assuming TCP/IP is enabled as primary and Named Pipes as secondary. When an application tries to connect to SQL SERVER, it first tries with TCP/IP. If that did not succeed, it tries with Named Pipes. If that also fails, then only it throws the error. However, we can force the application to use only one protocol and that is done by the "Network" keyword in

The strange thing is that in general establishing the connection isn't a problem but so now and then this error pops up. I'm using SQL authentication over a TCP/IP connection which are defined in an UDL file. We've tried connection using a DNS name or an IP number but that doesn't matter. I'm using: - MS SQL Server 2000 sp3 - IIS 6.0 - ASP - MDAC 2.6 can anybody help me out? TIA Cheers, Friso The Following User Says Thank You to Ja
