Early indications show me that State 16 is an old, generic message, meaning the db couldn't be opened. Either the user lacks permissions or the server is inaccessible: sqlblog.com/blogs/aaron_bertrand/archive/2011/01/14/… –Danny Beckett Mar 20 '13 at 5:28 add a comment| 2 Answers 2 active oldest votes up vote 0 down vote I've seen this in the past. After researching around we found that this was due to the user not having permission to login to the database that has been setup as their default. It was a newly setup DB user for use by SSIS imports. We used ALTER LOGIN to resolve the issue. ALTER LOGIN [username] WITH DEFAULT_DATABASE = [database name] Note: This was using SQL Server 2008 but it should be the same for 2005. share|improve this answer answered Mar 20 '13 at 7:02 Gibr

x) with SQL Server ★★★★★★★★★★★★★★★ Sakthivel ChidambaramFebruary 6, 20116 0 0 0 I know that there are lot of articles over the internet world with this topic… But this article is from my perspective which has detailed troubleshooting steps… The main problem with troubleshooting connectivity issues with SQL Server is because the error message returned to client is almost generic and incase of login failures, the state is always 1 So let me give you step-by-step approach in troubleshooting connectivity issues with SQL Server. Here is a flow of how connection to SQL Server is made: 1. Protocol used for making connections to SQL Server Connecting is made using a protocol based on the "Client Protocols" order specified in your local box. In the case of screenshot given above, the connection made to any SQL Server fromthis client machinewill use "Shared Memory" protocol first and if that connection fails, it will try to use "TCP/IP" protocol and if that fails, connection request will be made using "Named Pipes" protocol. This is because I have all three protocols "Enabled" and I have specified the order in this way. Shared Memory protocol can be used only for local server connections whereby SQL Server should be running in the same box where you are trying connect. This protocol will not help you to connect to a Clustered SQL Server instance because the IP address of SQL Server is different from your local node. You can also force to use specific protocol using syntax: TCP:SQLSRVRNAME\INSTANCE for forcing connections to use TCP/IP protocol NP:SQLSRVNAME\INSTANCE for forcing connections to use Named Pipe protocol instead you can also use \\.\pipe\instancename\sql\query LPC:SQLSRVNAME\INSTANCE for forcing connections to use Shared Memory protocol. LPC stands for Local Procedure Call. If you force these protocols, then connectivity will happen only using specific protocol and if that fails, connection will fail without trying with further protocols. If you are connecting using a SQL Server alias created in the local client, then the protocol specified in the alias will only be used. 2. Connecitivity flow when using TCP/IP Protocol While making connections using TCP/IP protocol, the client driver will check whether the instance is DEFAULT instance (MSSQLSERVER is the instance name for default instance) and if yes, the connection is made directly to port 1433 using TCP protocol
