SharePoint 3.0: Overcoming Upload Limits and Timeouts

The following instructions are recommended for overcoming out of box limitations related to uploading documents. These configurations are done once per web application and are not global changes.


1. Central Administration > Application Management > SharePoint Web Application Management > Web Application General Settings > Maximum Upload Size: Change to 2047 MB (Maximum)


2. Internet Information Services Manager > Web Site > Right-Click > Properties > Connections: Change Setting (e.g. 600 seconds)


3. Windows Explorer > Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\Template\Layouts\ > Web.Config

Replace This:

httpRuntime maxRequestLength="2097151"

With This:

httpRuntime executionTimeout="999999" maxRequestLength="2097151"


4. Web.Config Continued...

Replace This:

httpRuntime maxRequestLength="51200"

With This:

httpRuntime executionTimeout="999999" maxRequestLength="51200"


5. Windows Explorer > INET PUB\WWWRoot\VirtualDirectories\WebApplication\ > Web.Config

Add the snipet from http://support.microsoft.com/kb/944981%20BconfigSections between the "configSections" closing tag and the "SharePoint" opening tag (like Shane suggests in his post).
