[Microsoft][ODBC SQL Server Driver][SQL Server]Login Failed For User 'ErrorLog'.

Hi, all

recently, I use the following script(somebody else) to create a database on a remote server: the script is as follow:
/*************************/
CREATE DATABASE [ErrorLog]
GO

Use ErrorLog

CREATE TABLE [dbo].[Errors] (
[ID] [int] IDENTITY (1, 1) NOT NULL ,
[SessionID] [char] (12) NULL ,
[RequestMethod] [char] (5) NULL ,
[ServerPort] [char] (5) NULL ,
[HTTPS] [char] (3) NULL ,
[LocalAddr] [char] (15) NULL ,
[HostAddress] [char] (15) NULL ,
[UserAgent] [varchar] (255) NULL ,
[URL] [varchar] (400) NULL ,
[CustomerRefID] [varchar] (20) NULL ,
[FormData] [varchar] (2000),
[AllHTTP] [varchar] (2000),
[ErrASPCode] [char] (10) NULL ,
[ErrNumber] [char] (11) NULL ,
[ErrSource] [varchar] (255) NULL ,
[ErrCategory] [varchar] (50) NULL ,
[ErrFile] [varchar] (255) NULL ,
[ErrLine] [int] NULL ,
[ErrColumn] [int] NULL,
[ErrDescription] [varchar] (1000) NULL ,
[ErrAspDescription] [varchar] (1000) NULL ,
[InsertDate] [datetime] NOT NULL
) ON [PRIMARY]



--Create the user "ErrorLog"

if not exists (select * from master.dbo.syslogins where loginname = N'ErrorLog')
BEGIN
declare @logindb nvarchar(132), @loginlang nvarchar(132) select @logindb = N'Navigator', @loginlang = N'us_english'
if @logindb is null or not exists (select * from master.dbo.sysdatabases where name = @logindb)
select @logindb = N'master'
if @loginlang is null or (not exists (select * from master.dbo.syslanguages where name = @loginlang) and @loginlang <> N'us_english')
select @loginlang = @@language
exec sp_addlogin N'ErrorLog', 'secret', @logindb, @loginlang
END
GO

if not exists (select * from dbo.sysusers where name = N'ErrorLog' and uid < 16382)
EXEC sp_grantdbaccess N'ErrorLog', N'ErrorLog'
GO

Grant select, insert On Errors to ErrorLog
/***************************/
in my *.asp program, I used the following string to connect to the database on the remote server.
/********
con.open "dsn=ErrorLog;uid=ErrorLog;pwd=secret;"
********/
the following message comes up:
/********/
Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80040E4D)
[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'ErrorLog'.
/*********/
what is the problem here?
when I set up dsn ErrorLOG, I used "abc" userID and password "XXX" which is our server database administrator assigned to me. I tested connection in odbc, it is OK
I just don't get, ther user ErrorLog already had login id and granted access to database errorlog. any clue, please help!
