尝试连接到 SQL Server 时出现经典 ASP 错误 80004005

Question

I am trying to connect a classic ASP webpage to SQL Server 2008, and whatever I do I keep getting this...

error '80004005'

It then proceeds to tell me the line where the error is, and that is all.

My connection code is as follows

<%
Dim Stock
Dim Stock_cmd
Dim Stock_numRows

Set Stock_cmd = Server.CreateObject ("ADODB.Command")
Stock_cmd.ActiveConnection = MM_DVerto_STRING
Stock_cmd.CommandText = "SELECT Location, Part_Number FROM dbo.Stock_Header WHERE Part_Number = ?" 
Stock_cmd.Prepared = true
Stock_cmd.Parameters.Append Stock_cmd.CreateParameter("param1", 200, 1, 15, Stock__MMColParam2) ' adVarChar

Set Stock = Stock_cmd.Execute
Stock_numRows = 0
%>

Connection File

<%
' FileName="Connection_odbc_conn_dsn.htm"
' Type="ADO" 
' DesigntimeType="ADO"
' HTTP="false"
' Catalog=""
' Schema=""
Dim MM_DVerto_STRING
MM_DVerto_STRING = "dsn=CMD SQL;uid=web;"
%>

Any help would be greatly accepted!

Error 80004005 is:

Data source name not found and no default driver specified

Most likely your web server is missing an ODBC connection named CMD SQL .

If not, here is the full list of possible causes from that MSDN link:

• The Microsoft Windows NT 4.0 or Windows 2000 user account that is used to process the request for the ASP page does not have sufficient permissions to read the registry key that stores the specified DSN's configuration information.
• The System ODBC DSN that is specified in the ADO connection string does not exist on the IIS server.
• The ASP Application or Session variable that is initialized in the ASP application's Global.asa file (or in an ASP page that is accessed before the page that contains the database connection code) is used to specify the ADO connection string. This connection string variable is not initialized when the code to open the database connection is run. To confirm this, add a Response.Write statement before the line of code that opens the database connection to display the connection string that is stored in the variable.
