Login failed for user 'Domain\MachineName$' asp.net app deployment

We are trying to deploy an asp.net app. to a Windows Server 2003 running SQL Server.  When we try to access the DB we receive the following error :-

Login failed for user 'Domain\MachineName$'

We "think" we have set all correct user logins but can't be 100% sure as we cannot find any finite documentation on this and what we have found seems to apply to "NetWork security" users and ASPNET users but nothing relating directly to the machine account.

Any thoughts would be much appreciated.

You will need to enable both Windows and SQL Server authentication in the SQL Server Properties. After enable that option, you can create a specific database user to connect to the SQL Server. If Windows Authentication is not used in ASP .NET app, then the SQL Server connection is accessed by ASPNET account that has very minimum privileges and under default installation, no permissions at all to access the SQL server. Visit http://www.connectionstrings.com to learn more about the connection string format.

Here is an example from connectionstrings.com web site:

Standard Security:

"Data Source=Aron1;Initial Catalog=pubs;User Id=sa;Password=asdasd;"
   - or -
"Server=Aron1;Database=pubs;User ID=sa;Password=asdasd;Trusted_Connection=False"
   (booth connection strings produces the same result)

 Trusted Connection:

"Data Source=Aron1;Initial Catalog=pubs;Integrated Security=SSPI;"
   - or -
   (booth connection strings produces the same result)

(use serverName\instanceName as Data Source to use an specifik SQLServer instance, only SQLServer2000)
 Connect via an IP address:

"Data Source=,1433;Network Library=DBMSSOCN;Initial Catalog=pubs;User ID=sa;Password=asdasd;"
(DBMSSOCN=TCP/IP instead of Named Pipes, at the end of the Data Source is the port to use (1433 is the default))
 Declare the SqlConnection:

using System.Data.SqlClient;
SqlConnection oSQLConn = new SqlConnection();
oSQLConn.ConnectionString="my connectionstring";

Imports System.Data.SqlClient
Dim oSQLConn As SqlConnection = New SqlConnection()
oSQLConn.ConnectionString="my connectionstring"

I will check the link out and report back...

Here is our connection string - is this wrong?

workstation id="JAMES-X31";packet size=4096;user id=sa;data source=R2D2;persist security info=True;initial catalog=Reality;password=MyPassword

Where R2D2 is the IIS6 / DB Server and JAMES-X31 is the development machine (does this matter).

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.
