TFS series-problems encountered during TFs re-installation

Recently, I tried to introduce vsts in the project (originally used to use cvs for simple version management), so installing team Foundation server is indispensable! During the first installation, we encountered the "source file loss" problem. For details, see the TFS series-root cause of file loss during the installation process.
