Changing Maximum Upload Size in WSS 3.0 and MOSS 2007

Looking around the web, I found many articles describing how to do change the Maximum Upload Size in SharePoint, but for whatever reason, the options in the instructions were not available on my SharePoint installation. Blog posts by Joel Oleson on File Name, Length, Size and Invalid Character Restrictions and Recommendations and this one by Ronnie Guha mention the "Configure Virtual Server Settings" area on the "Virtual Server List" page in Central Admin. Neither of these existed. After some poking around, here is the correct navigation for WSS 3.0 and MOSS 2007. I'm not sure when in the builds of WSS that this change occurred, so follow the set of directions apply to the options you have available.

1. Open Central Administration
2. Open the Application Management tab.
3. Choose Web Application General Settings (take note that the url is /_admin/vsgeneralsettings.aspx - that appears to prove its legacy in Virtual Server).
4. Scroll down until you find the section labeled Maximum Upload Size.
5. Change away.

There is an element in the web.config called httpRuntime. The maxRequestLength attribute (defaulted to 51200) is traditionally used to change the maximum file upload size in ASP.NET web applications, but does not appear to have any effect on SharePoint.

I highly recommend you take a look at Joel's post on this topic to get an idea of how you should set that value based on your needs, but these instructions should take you the rest of the way.
