When trying to upload files over 200KB on IIS 6 the file may never upload and you either get an error or are sent to a blank screen. By default Windows 2003 server limits file uploads to about 200KB in size. To overcome this limit you must edit the IIS metabase.xml file.
Before you can edit the metabase.xml file you must tell IIS to allow you to edit the file. In IIS, right click the name of the server and select properties. Check "Enable Direct Metabase Edit".
- Find the metabase.xml file located in C:\windows\sytem32\inetserv and open the file in Notepad.
- Search for AspMaxRequestEntityAllowed and increase the value. The default value is 204800 (200K). Setting the value to 1000000 will allow 1 MB file uploads.
- You may now wish to uncheck the IIS property called "Enable Direct Metabase Edit".
To increase the file download size limit, repeat all steps above but in Step 3 find the parameter called AspBufferingLimit. The default download limit is 4MB.
In Classic ASP
If you are getting this issue in Classic ASP Page then to resolve this issue, modify the value in the AspMaxRequestEntityAllowed property to set the maximum number of bytes that are permitted in the entity body of an ASP request. To do this, follow these steps:
1. At a command prompt, type the following command, and then press ENTER:
cd drive:\inetpub\adminscripts
Note In this command to change folders, drive is a placeholder for the hard disk where IIS is installed.
2. At a command prompt, type the following command, and then press ENTER:
cscript adsutil.vbs set w3svc/ASPMaxRequestEntityAllowed size
Note In this command, size is a placeholder for the largest file size upload that you want to allow. The maximum value is 1,073,741,824 bytes. Set this value to the lowest possible value that allows for the functionality that you want.
3. At a command prompt, type the following command, and then press ENTER:
iisreset
