How To Add Record Into SQL Server 2000?

How can I add the record into my company SQL Server 2000 database from the website register page???

This is my codes:
<%
Dim sql,rs

Dim objConn
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=c:InetPubwwwrootdalyfpdbmarket.mdb"

sql="INSERT INTO testing (fname,lname)"
sql=sql & " VALUES "
sql=sql & "('Shawn', 'mike')"

objConn.Execute sql
objConn.close
%>

This is my error:
Microsoft JET Database Engine error '80004005'

Operation must use an updateable query.
