Files and Permissions for SharePoint 2007
Last week while troubleshooting some rights and permission issues for groups in SharePoint, I found myself on this little gem of content.
It covers the installation directory, windows directory, site directories, registry settings, databases, etc… what they are for a SharePoint installation, and the appropriate permissions. Definitely great reference resources when troubleshooting.
