Question : Difficulty uploading items larger than 1 MB

I recently created a website where our vendors upload various electronic documents (.pdf, .fnm, .jpg, etc.) so we can process files quicker.  A strange problem has revealed itself:  Files less then 1MB in size can be upload without issues, but if the file is larger then 1MB the website requests a username and password be entered.  I have tested this issue both inside and outside of our LAN, and it trully does exist.  My website sits on a Windows Server 2003 box and the website was created using Microsoft FrontPage 2003.  The website is running on IIS 6.  I have the website pemissions set to:  Anonyous w/Contributor.  I have spent the better of two hours looking over the website and server and cannot find anything that is causing this issue.  Any help would be greatly appreciated!!!!

Answer : Difficulty uploading items larger than 1 MB

There are tons of ASPupload components out there that you can use like ABCupload, SmartUpload, etc....  But I think also Serv-U just came out with a version 7 that supports web based uploads.

Yup, just checked it...they support it.
