| Problem Description:
| By default, the Windows 2003 server setting AspBufferingLimit in the metabase.xml file is set to disallow downloads of filesizes greater than 4 mb. | Resolution:
| Follow these steps to edit the metabase.xml file in order to allow larger downloads: - Open Computer Management
- Right Mouse Click on My Computer and click Manage OR
- Click Start -> All Programs -> Administrative Tools -> Computer Management
- Backup the IIS Metabase - see Backing Up and Restoring the IIS Metabase
- Enable Direct Metabase Editing
- In the Computer Management Window, Right Mouse click on Internet Information Services
- Click Properties
- Check "Enable Direct Metabase Edit"
- Click Apply and OK
- Edit the IIS Metabase file
- Open Windows Explorer
- Browse to the "c:\windows\system32\inetserv\" directory
- Right Mouse click on the file "metabase.xml" and Open With NotePad
- Find the property "AspBufferingLimit"
Note: The default value is 4194304 (approx 4 mb) which will only allow files smaller than 4 mb to be downloaded in an ASP web application.
- Change the value from "4194304" to whatever limit is reasonable for the types of files your users will be attaching.
- Save the file and close NotePad
- Disable Direct Metabase Editing (for security reasons)
- In the Computer Management Window, Right Mouse click on Internet Information Services
- Click Properties
- Uncheck "Enable Direct Metabase Edit"
- Click Apply and OK
