[RESOLVED] File download

[dbasnett]

I have used the following code for several years and never had an issue down loading .docx file from our web site to the user.

                    Dim fi As New IO.FileInfo(FileName)
                    'Resp is a HttpResponse from DwnLD.aspx.vb
                    Resp.Clear()
                    Resp.ClearHeaders()
                    Resp.ClearContent()
                    Resp.AppendHeader("Content-Disposition", "attachment; filename=" & IO.Path.GetFileName(FileName))
                    Resp.AppendHeader("Content-Length", fi.Length.ToString())
                    'hmmm....
                    '                   "application/octet-stream"
                    'for .docx files
                    '                   "application/vnd.openxmlformats-officedocument.wordprocessingml.document"
                    ' Resp.ContentType = "application/vnd.openxmlformats-officedocument.wordprocessing*?ml.document"
                    Resp.ContentType = System.Web.MimeMapping.GetMimeMapping(FileName)
                    Resp.TransmitFile(FileName)
                    Resp.Flush()

We recently updated the server and now users can't download the files. We get a file name and network error in the download files drop down. Don't have the error when running in the development environment.

Windows server version - 24H2
IIS Version - 10.0.26100.1

Any help is appreciated. THX

First thing I would check is the IIS logs to see what (if any) errors/error types are being logged in these cases. Is it possible that they are just 404'ing due to some sort of path change due to the server upgrade?

What was upgraded? The OS on the same hardware? Or a full server replacement?

It could be as simple an issue like the MIME type for .docx just needs to be added in IIS.

Checked the log, no errors.

It was a full server replacement.

We checked the MIME type and .docx is there.
