SQLException: unexpected pre-login response.

Posted By: bansidhe     Posted Date: February 15, 2011    Points:2   Category :Sql Server

I just updated the sqljdbc jar file to be used to access our SQLServer2005 and 2008 servers. (Going from

Microsoft 2005 SQL Server JDBC Driver/.../sqljdbc.jar
Microsoft SQL Server JDBC Driver 3.0/.../sqljdbc4.jar


I can connect without issue to the 2005 and 2008 servers.

However when I try to connect to our SQLServer 2000 server I get the following SQL Exception error.

The TCP/IP connection to the host xxx, port 1433 has failed. Error: "The driver received an unexpected pre-login response. Verify the connection properties and check that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. This driver can be used only with SQL Server 2000 or later."

ANy direction would be most appreciated.
