Microsoft SharePoint project portal problems with Microsoft Team Foundation Server 2010

You should first verify proper connectivity between the TFS application tier machine(s) and those hosting SharePoint. Then, using the Team Foundation Server Administration Console, verify that the SharePoint Web Applications entry for the Application Tier and SharePoint Web Application in question are established and working. You can use the "Repair Connection" option to confirm this:

1. Open the Team Foundation Server Administration Console
2. Expand the Application Tier in question (the one hosting the Team Project Collection and Team Project with the problem)
3. Highlight the SharePoint Web Applications node.
4. In the SharePoint Web Applications list, highlight the appropriate connection and then click "Repair Connection"

While you are here, verify the membership in the Service Accounts for SharePoint Web Applications as well. 

If the "Repair Connection" is successful, next verify the Portal Settings for the Team Project in question. You access this by connecting to the Team Project using Team Explorer. Then, right-click the Team Project name and select "Team Project Settings..." followed by the "Portal Settings..." option. Ensure the values here are correct.

You may also need to update your Alternate Access Mappings in SharePoint (see the More Information section below for details on this).

Also verify that in the “Extension for SharePoint Products” in TFS Administration Console section, make sure that the “Integration Target” column is pointing to the new or fully qualified domain name that you expect in the Team Web Access URL for the TFS Sharepoint portal.

To modify:

- Click and highlight the row, select “Modify Access”.

- Then update the “URL for Team Foundation Server” accordingly.

- Click OK, and then test to see if the TSWA URL is now updated.

If the SharePoint Web Applications connection, Portal Settings, and Alternate Access Mappings are all correct and you are still experiencing issues, you may be missing permissions for the [TEAM FOUNDATION]\SharePoint Web Application Services group to the team project.

As part of TFS Team Project creation we allow READ on the catalog nodes for the team project for the [TEAM FOUNDATION]\SharePoint Web Application Services group. However if at some point you explicitly add this group and then remove it from the Team Project permissions, the act of removing it will remove ALL permissions for this group, including the implied READ on the catalog from when the project was created. This may be the cause of your issues.

To repair this missing permission, add the [TEAM FOUNDATION]\SharePoint Web Application Services group to the permissions of the TFS Team Project experiencing the issue:

• Use Team Explorer to connect to the Team Project with the issue.
• Right-click on the Team Project name and then select Team Project Settings... Security.
• Select the "Team Foundation Server Group" option in the "Add users and groups" section, and then click Add.
• Select the "[TEAM FOUNDATION]\SharePoint Web Application Services" and add it.

Test the portal for the Team Project. If it doesn't work on first run, use tfsredirect.aspx to refresh the cache. For example, if the portal site address is http://SharePointServer/sites/TeamProjectCollectionName/TeamProjectName, you would navigate to the following address in your web browser: 
http://SharePointServer/sites/TeamProjectCollectionName/TeamProjectName/_layouts/TfsRedirect.aspx?tf:type=webaccess&tf:test=1&tf:clearcache=1. This will force a refresh of the SharePoint information about the TFS Team Project specified. This page should not return any errors and the value for TeamFoundation.Temp.LastRefreshDate should include the current date.

NOTE: If adding the [TEAM FOUNDATION]\SharePoint Web Application Services group to the permissions of the TFS Team Project resolved your issues it must remain there. If you remove that group the issues will return.
