error:26 Error Locating Server/Instance Specified

I am having trouble connecting to Sql Server 2005 Express from asp.net
2.0 app on Windows Server 2003. I am using Sql Server Authentication,
and I tried the below article's suggestions a number of times. When I
login to to the machine, and login, I am able to get authenticated.
However, when I debug my application, I get the error below. Do I have
to give the sql server authenticaed account I created certain
permissions? Whould I set a port, and use the ipaddress rather than
the server name? Any suggestions would be greatly appreciated.

My 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: SQL Network Interfaces, error: 26 - Error
Locating Server/Instance Specified)
My Connection String:
<add key="ConnectionString"
value="server=MyServerName;uid=MyUserName;pwd=MyPasswd;database=MyDB"/>On Feb 1, 5:20=A0pm, carlos <carlosubu...@.gmail.com> wrote:

Update:
I changed the connection string to use the ipaddress, and a port that
I set in the TCPIP settings, and now i'm getting the below message:
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'm thinking this may be a permission problem'|||Hi Carlos,
By default, SQL Server 2005 Express, Evaluation, and Developer editions
allow local client connections only. Enterprise, Standard, and Workgroup
editions also listen for remote client connections over TCP/IP.
you ned to enable Remote Connections option using
Surface Area Configuration for Services and Connections (Remote Connections)
- Database Engine
You must restart the Database Engine instance's service to apply changes.
