This is a really obscure error message when SharePoint search is not working on your site (thanks Microsoft). And, really, unless you know what’s going on, there’s really no way to troubleshoot this one. When you or users are trying to perform a search and you are getting the error message:
“Unknown Error. Troubleshoot issues with Windows SharePoint Services.”
Go to: Central Administration -> Operations -> Global Configuration -> alternate access mappings.
Add the your website’s website via the Add internal URLS button and set it to Internet.
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.
This script backs up everything you need for a full restore of your Windows Sharepoint Services (WSS) or Microsoft Office Sharepoint Server (MOSS).
