Sql-server – CLASSIC ASP – SQL Server does not exist or access denied

asp-classicsql server

I'm trying to make a connection to a SQL Server Express DB on localhost, but I get the following error message:

Microsoft OLE DB Provider for SQL Server (0x80004005)

[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or
access denied.

The code I'm using is

Dim connection 
Set connection = CreateObject("ADODB.connection") 
connection.connectionString = "server=localhost;Provider=SQLOLEDB;Data Source=RiskManagement;Initial Catalog=RiskManagement;User ID=sa;Password=myPass;" 
connection.Open()

Any ideas?

First thing to always check is that you have configured SQL Server to allow remote connections.

How to configure SQL Server 2005 to allow remote connections

For generic SQL Server Connectivity Troubleshooting consult the following Blog Post

Syntax:

ALTER TABLE {TABLENAME} 
ADD {COLUMNNAME} {TYPE} {NULL|NOT NULL} 
CONSTRAINT {CONSTRAINT_NAME} DEFAULT {DEFAULT_VALUE}
WITH VALUES

Example:

ALTER TABLE SomeTable
        ADD SomeCol Bit NULL --Or NOT NULL.
 CONSTRAINT D_SomeTable_SomeCol --When Omitted a Default-Constraint Name is autogenerated.
    DEFAULT (0)--Optional Default-Constraint.
WITH VALUES --Add if Column is Nullable and you want the Default Value for Existing Records.

Notes:

Optional Constraint Name:
If you leave out CONSTRAINT D_SomeTable_SomeCol then SQL Server will autogenerate
a Default-Contraint with a funny Name like: DF__SomeTa__SomeC__4FB7FEF6

Optional With-Values Statement:
The WITH VALUES is only needed when your Column is Nullable
and you want the Default Value used for Existing Records.
If your Column is NOT NULL, then it will automatically use the Default Value
for all Existing Records, whether you specify WITH VALUES or not.

How Inserts work with a Default-Constraint:
If you insert a Record into SomeTable and do not Specify SomeCol's value, then it will Default to 0.
If you insert a Record and Specify SomeCol's value as NULL (and your column allows nulls),
then the Default-Constraint will not be used and NULL will be inserted as the Value.

Notes were based on everyone's great feedback below.
