The Central Administration Page and Site Collection is setup and working, but I am unable to active site features.

Sharepoint is setup on a separate server from TFS. I installed Sharepoint extensions on the remote server. I granted permissions.

On the TFS server, I pointed everything to the remote server, but I still have this error.

Reconnecting SharePoint Web application at the following address: http://xxxxx/.
[Warning] TF205021: A feature could not be activated in the following Web application: http://xxxxx/. The feature is Tswa. This feature is part of the following solution: TswaWebPartCollection.wsp. Without this feature, project dashboards will not function correctly. Verify that the solution has been deployed to the SharePoint farm, and that the feature has been activated in SharePoint Central Administration. The server returned the following error: TF250035: A feature for SharePoint Products could not be found with the following ID: 60e22958-ba2a-47be-b995-820c756324b6.

I only have one sharepoint server and one TFS server.

Not sure what I am missing.

Hi,

According to your description, you need to add and deploy the wsp on the sharepoint server and activate the feature on the site.

You can navigate to the site settings page by adding /_layouts/settings.aspx next to the web application.

Hope the helps :)
