Code works Fine on Win2000 IIS 5 but not on Win2003 IIS6

[Razarr69]

I have a ASP application that I am using for my company and it is
currently running on a Windows 2000 server box with IIS 5. The code
works perfectly there (except for handling large files - due to low
amount of RAM, I hope anyway - thus the switch to the new server).
Now I need to move the application to a better server. My hope was to
just copy the folder to the new server and get running. This almost
worked. :(
The pages seem to work fine until I go to upload or download a
document. I know the ASP is accessing the SQL Server database it
pulls/pushes data to because users can log in and make changes to the
DB without issue (log in requires checking usernames and passwords from
the SQL Server 2000 DB). The Database has not moved as it is housed on
a separate Server that just handles the SQL Server side. Users can
pull table data and change data using the other pages of the site as
designed.
Then the fun starts...
Normally the user requests a list of documents that meet certain
requirements and the system returns a table that has all of the
documents requested. The user then clicks on the name of a document
and this switches the user to another webpage that pulls the document
from the DB. What happens in the background on the IIS server is the
document is pulled into a subfolder of the webite called Images. Then
the user's browser is redirected to that file, triggering a download in
most instances or the file may open inside their IE browser if it is a
pdf or whatever. Problem is, the inital write to file fails. The
document is not being created and all the user will see is a :
HTTP 500 - Internal server error
Internet Explorer
No error message other than that, even though the IIS is set to send
detailed error messages to the browser.
I have set the permissions on the folder to be Full Control for
EVERYONE, IUSRaccount, and IWAMusr account. In IIS we have anonymous
access enabled and Integrated security. For the website and folders we
have all of the visible settings set exactly like they were on the
Windows 2000 / IIS 5 box. But it still refuses to work.

I am at a total loss. My technical guru at my contracting company
mentioned something about it being possibly related to COM Object
read/create issue, but I do not know anything about setting a permisson
for that.

What has changed in IIS 6 that is killing my code. If need be I can
post the code that should generate a download. The upload portion I
think will resolve itself once the download issue is addressed as it
seems to be a write to file failure. (Actually we saw this error listed
when we loaded the code into dreamweaver and checked it there on the new
server)

Any help would be GREATLY appreciated.

Thanks,

Or perhaps not. You indicated a "problem" with large files and an "upload
problem", but I can't tell if those are one and the same. If so, read this
(especially the last part):
