A very strange Permission Denied error with CDONTS

I've seen a lot of postings regarding this error, but haven't found
any solution applied to my case. In our application, a user will get
two emails. One is the email with password after he signs in; and
after he finishes certain transactions, a second email will be sent as
confirmation.

Both emails work fine in our development, but in production, only the
first email works; the 2nd generates the Permission Denied error when
the send() function of CDONTS.NewMail is called. Since the first email
has always been sent out successfully, there shouldn't be any problem
with the mailroot directory or SMTP server on the production. The
send() of the first email is called in an asp file, and the 2nd is
called in a DLL. The asp and the DLL are placed in different folders.
I compared the rights of the two folders, and also compared the
folders between the development and the production, and I can't find
anything different.

Both development and production run on Windows 2000 server with IIS 5.
We don't use Exchange server. The only difference that I know of
between the two servers is the development has SP4 while the
production has SP3.

Does anyone have suggestion on which directory the permission may be
denied for? Thanks in advance!

It's probably the Mailroot/drop directory that's the problem.
If the web is an application in high isolation then it's using the iwam
account for cdonts.
Not sure why only 1 works though.
