As part of upgrade, you might decide on upgrading SharePoint from 2.0 to 3.0. The SharePoint upgrade requires a prerequisite step of running a tool called “prescan.exe” which is shipped along with the WSS 3.0 redistributable or can be downloaded here.

When you run the tool, you might see this error:

Error: Prescan has encountered sites or lists that were not updated because they cannot be accessed using the SharePoint Products and Technologies object model. The most likely reasons for Prescan to skip a list are covered in the Knowledge Base article at: http://go.microsoft.com/fwlink/?linkid=69958&clcid=0x409.

Cause

One of the sites that the pre-scan tool is failing on is using a SFTS template (scrum for team system.)

The issue shows itself after an upgrade to TFS 2008. The symptom can be felt when you try to browse the project portal site with existing SFTS 1.2 template, the site shows a 404 error.

This has been caused by the removal of files required for the WSS template.

Resolution

1. Backup the following folders:

Program files\Common Files\Microsoft Shared\Web Server Extensions\12\Template\Layouts [ if present - might have been deleted already during upgrade ]

Program files\Common Files\Microsoft Shared\Web Server Extensions\60\Template\1033

2. Download this file and extract it into Program files\Common Files\Microsoft Shared\Web Server Extensions. The zip contains the relevant paths to the files it needs to copy.

3. Run an IIS Reset.

Now the site should start using the SFTS templates. Run the Prescan tool it should run successfully
