Don't use components - use free ASP files ... like here:

asp uploader: a useful script made up of three asp files for website developers and web masters. When installed correctly on your Microsoft IIS web server, the three ASP (Active Server Page) files will allow your users the ability to upload files to the web server. There are no components to install.
asp-uploader.zip contains -
1) uploadform.asp: This file allows the user to select the file (from their computer) to upload to the web server. Once they select the file they want to upload, they click the upload button and the form calls the uploadexmple.asp
2) uploadexmple.asp: This page takes the file to be uploaded and performs the actual uploading process by using an Upload function within the upload.asp file. Once the upload is complete, this form displays the confirmation message (or error message).
3) upload.asp: This file contains the FileUploader class and the UploadedFile class. These classes are used to perform the actual upload from the client machine to the web server.
Instructions to install -
1) Place all three ASP files under the same folder within an IIS virtual directory (on your website). Note: The web folder that the ASP files reside in MUST have permission to create text files. Check these permissions in IIS.
