Cannot connect to SQL Server 2005 From Management Studio - target machine actively refused it

I am trying to connect to the my SQL Server 2005 database with SS Mangement Studio.

I get this error:

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: TCP Provider, error: 0 - No connection could be made because the target machine actively refused it.)

I also get the error when I try to run ASP.net app from my local machine. Everthing works find in the discount ASP.net environment.
Thistheconnection data/string:
"Data Source=tcp:sql2k5**.discountasp.net\;Initial Catalog=SQL2005********;User ID=*******;Password=*****;" providerName="System.Data.SqlClient"/>

 

That slash should not be there,should be like this:

Data Source=tcp:sql2k510.discountasp.net;

 

I removed the slash and I get the same error.
Thx

Seems your OS may be locking down the security.
