Hi HuaMinChen
The following is an example of basic connection string referencing System DSN:
DSN=myDsn;Uid=myUsername;Pwd=;

The 'Uid' should be the user name associated with the DSN

So if the DSN pointed to a SQL Server database, then the Uid would be the SQL Server user/login

Please let me know if this helps

Barry,
I put Windows account below (as database user and password is already System DSN)

but then it is not prompting me with the password (which I expect to happen).

As we're using Third-party report tool (called Ariacom), which is deploying web report using their DLL file, on IIS. It is depending on System DSN and is running fine within Win 2003 server. Now within Win 2008 server, how can I refer to relevant System DSN in above?

If you're using an AD Account then you can't provide an UID and PWD, since those fields are only for SQL Server logins.
For AD Accounts you'll need to use Trusted Connection or Integrated Security options (it will use the credentials of current logged user).
