I have gone to windows firewall and applied an allow rule on inbound and outbound for port 1433. When I perform a netstat -an command that port is not shown as listening, when I try to connect to the server using another application that requires that port it is not connecting. It is a domain environment with an SBS2k11, WSS2K8 (SQL server), Linux server (cannot connect on port 1433). The SQL server and Linux server sit on the same vsphere server; the domain controller has its own dedicated hardware.
There is no firewall in-between however it cannot connect.
Look forward to reading your comments!
