Error while connecting to SQL Server from Server 2012 R2 machine


hi,

i trying connect sql server located on machine ip 172.16.xxx.xx remote machine i.e windows server 2012 r2 machine, each time error shown below. have added port 1433 in firewall inbound settings , enabled it. doesnt shown in list when netstat /a. need immeadiately resolve issue,thanks. 

1. make sure sql server service running
2. if named instance, make sure sql server browser service running
3. make sure sql server configured allow remote connections
4. examine sql server error log messages confirming sql listening on expected network interfaces , ports
5. test server connectivity ping client machine
6. test port connectivity using telnet or powershell server , port (from step 4) client machine.  for example
a. telnet <server-name> 1433
b. powershell: 1433 | % { echo ((new-object net.sockets.tcpclient).connect("yourservername",$_)) "server listening on tcp port $_" }
7. check firewall settings if step 5 or 6 connectivity test fails
