Problems downloading large files

One of my users can't download over 5 MB files (ppt). Smaller files are fine. I've tested all IE browsers and Firefox and it works. User uses IE7. It's a local issue obviously specific to that particular user.

Server environment: IIS 7, asp.net, framework 2.0. Any ideas how i can troubleshoot it?

protected void Page_Load(object sender, EventArgs e)
{
...
if (metadata != null)
{
                    Response.ContentType = FileExtUtils.GetMimeType(metadata.FileExt);
                    Response.AppendHeader("Content-Disposition", 
                        String.Format("attachment; filename=\"{0}\"", Path.GetFileName(metadata.FileName)));
                    Response.Expires = 0;
                    Response.Buffer = true;
                    Response.Clear();
                    Response.WriteFile(VirtualPathUtility.ToAppRelative(AppMembers.GetBinaryVirtualPath()
                        + "\\" + Path.GetFileName(metadata.FileName)));
                    HttpContext.Current.ApplicationInstance.CompleteRequest();
}
 
}

Hi

In the web.config file - add

<httpRuntime maxRequestLength="51200" />

Or

<httpRuntime executionTimeout="999999" maxRequestLength="51200" />

Note : 51200/1024 Kb= MB

rkworlds, thanks for quick response! Correct me if i am wrong but as far as i know maxRequestLength is for uploads, not downloads and designed to prevent DOS attacks. My user has issues downloading files.

So if this particular user uses FireFox, it works? it's only IE7 that is "broken"?
If it's that specific to one user and one browser...have you done the usual PC maintenance?
(Clear out the browser cache, empty recycle bin, defrag, etc.)

i did all that. no luck. any other ideas?

Just to confirm...this user can use a different browser and it works...it's only when this user uses IE7 that it doesn't work?
