SQL server remote connection enable

Question

I am able to do remote enable sql server 2008 through the following way:

1. All sql service start
2. TCP/IP enable
3. Named Pipes enable
4. set TCP port(1433) and UDP port(1434) through the windows firewall
5. Set TCP port(14792) of sql server.

But this problem has been solved in some network.....

I have tried to solve in another office by same procedure but failed

If any satisfactory answer to solve the problem to anyone...
