Summary

Troubleshoot issues with Microsoft SharePoint.

Cause

When installed, Windows SharePoint Services and SharePoint Portal Server 2003 automatically create a filter that intercepts requests normally handled by IIS. This prevents users from accessing other web applications that may be installed on the same server computer, e.g. WebLink.

Resolution

Configure SharePoint to ignore WebLink.

To configure SharePoint to ignore WebLink

1. Click Start, click Administrative Tools, and then click SharePoint Central Administration.
2. In the Virtual Server Configuration area, click Configure virtual server settings.
3. On the Virtual Server List tab, click the virtual server that you have to add the excluded paths to.
4. Under Virtual Server Management, click Define Managed Paths.
5. In the Add a New Path section, type the path that you want to exclude in the Path box. This will be the path to your WebLink installation folder.
6. Click Excluded Path, and then click OK

It some situations, it may also be necessary to edit WebLink's Web.config file in order to force WebLink to override SharePoint. For detailed instructions on the code that you may have to add to WebLink's Web.config file, please see the following Microsoft Knowledge Base article:

Note: The Web.config file is located in the Web Files subfolder of the WebLink installation folder
