Error in client installation
During client setup installation the message "u201Csetup has failed to automatically login to the server please enter correct login informationu201D appears and it does not allow the completion of the installation.
We are using MSSQL Server 2005 in Windows 2003 server domain environment. The ODBC driver installation on the client PC is installed successfully and the connection to SQL is OK.
Could you check whether SQL native client is installed, if not install the native client in the workstation and then try to run the client setup.
Also, you could download the native client from the below mentioned link.
If you still get the error, let me know which version you are using.
