Cause This problem occurs because the file size of the downloaded file exceeds the buffer limit of IIS.
Resolution: In order to resolve this issue, you must raise the buffer limit. This only needs to be done once for everyone who uses the web server. To raise the buffer limit:
1. In IIS, right-click the name of the web server and select Properties.
2. Select the Enable Direct Metabase Edit checkbox and click Save .
3. Go to C:\windows\system32\inetserv and open the metabase.xml file in Notepad.
4. Search for AspMaxRequestEntityAllowed and increase the file upload size limit. Note: Setting the value to 10000000 will allow for 10 MB file uploads. The default value is 4 MB.
5. Search for AspBufferingLimit and increase the file download size limit. Note: Setting the value to 10000000 will allow for 10 MB file downloads. The default value is 4 MB.
6. Save and close the file.
7. Click Start > Run and type IIRESET.
8. Click OK . IIS services will restart and the issue is resolved.
Note: For security's sake, you may want to repeat steps 1-2 and uncheck the Enable Direct Metabase Edit checkbox.
