You receive "Cannot obtain WSS item tp_ID" error message when you try to connect to a workspace in Project Server 2003

You use Microsoft Internet Explorer to try to connect to a Microsoft Project workspace, such as a document or meeting workspace, that was extended by using a Microsoft Project workspace template through Microsoft Windows SharePoint Services. When you do this, you may receive the following error message: You may receive this error message when you try to use subsites that include, but that are not limited to, document workspaces.

This issue may occur if the Microsoft Project Workspace template was used to create the document workspace. The Microsoft Project Workspace template does not define any site properties for the subsite.

To work around this issue, update and then save the Project Server intranet server address and extranet server address in the Server Configuration section of Microsoft Office Project Web Access. When you do this, the subwebs are updated by using the correct URL locations.

To do this, follow these steps:

1. Log on to Project Web Access as an administrator.
2. Click the Administration page.
3. In the Server Configuration section, enter the new intranet and extranet server addresses at the bottom of the page.
4. Save the changes.
