Try each of the following steps in order until the error is resolved:

 
  1. Verify the SQL Server service is running on the server and attempt to login at the server
 
  • Determine the server's IP address and then attempt to PING the SQL server by IP address and by server name (DNS name) from a command prompt
    • If the PING by IP address fails, contact a qualified IT professional for assistance with TCPIP
  • If the IP Ping connects but the PING by server name fails or reports a different IP address than the one found on the server, contact a certified IT professional to address the name resolution problem on the DNS server, or, as a temporary fix, add information to the HOSTS file of problem machines
     
  • If a firewall exists between the web server and the SQL server, verify the correct port number is opened in the firewall
 
  • Telnet the port being used by SQL Server to verify the connection is possible
    • If Telnet connects, set the connection string to manually use this port
  • If Telnet fails, contact a qualified IT professional for assistance troubleshooting the telnet utility
