sqlserver does not exsist or access is denied

[d2005]

My computer is telling me lies is it

i have this in the webconfig

<appSettings>
    <add key = "oSQLConn"
    value="server=localhost;database=StoreProc;integrated security=SSPI"/>
    </appSettings>

this in my code behind

Public Sub getuser()
   
        oSQLConn1 = New SqlConnection(ConfigurationSettings.AppSettings("oSQLConn"))
 
        strSql = "EXECUTE sprShowUsers"
        objCmd = New SqlCommand(strSql, oSQLConn1)
        'Try
        oSQLConn1.Open()
        dataReader = objCmd.ExecuteReader()
        'bind to datagrid
        dgUsers.DataSource = dataReader
        dgUsers.DataBind()
 
        'Catch ex As Exception
        'Finally
        oSQLConn1.Close()
        'oSQLConn.Dispose()
        '   End Try

this is my stored procedure

CREATE PROCEDURE sprShowUsers
as
select towm
from tbUser
order by carreg
GO

im trying to fill a datagrid and learn how to use stored procedures
i have got my users for asp.net and isur in my database also
