I ran across this problem and thought I’d share. After much troubleshooting, I found that Sharepoint 3.0 on Windows 2008 is limited to 28MB file uploads – this includes multiple file uploads that, combined, equate to a total of 28MB.
There’s a fix or workaround for it, but you have to modify web.config file in the Sharepoint virtual directory.
To work around this problem, follow these steps:
- Use Notepad to open the Web application Web.config file. By default, this file is in the following folder:
Microsoft Windows SharePoint Services 3.0
- Navigate all the way down to the bottom of the web.config file, and right before the </configuration> tag, add the following code:
3. Save the file and upload larger files.
NOTE: you can modify the maxAllowedContentLength value to the limit of the file(s) size(s) you want to be allowable.
