cannot connect to sqlserver 2014 from remote clients

Hi All,

Im in the process of doing an upgrade to GP2015. Its working fine from the client on the server itself but when I try to connect from a client installed remotely I'm not able to connect to the sqlserver.

I already did the following

-disabled firewall completely for now on both the server and the workstations

-enabled tcp/ip in sql server configuration manager and turned off dynamics ports and set it to port 1433

- verified Allow remote connections to this server is enabled in Server Properties

But still the sql server isn't accepting remote connections.

Help please

Thanks!
