If you can't log in to a site using Frontpage (repeated prompts for username/password) or if you're getting the following error:
"Server error: The server extensions were unable to access the file frontpg.lck. Please check the file permissions"
will occur if the username you are trying to login with isn't assigned
to the root of the site in File Permissions. This includes users that
only have access to subwebs. Any user assigned to the FP extensions
must have full NTFS permissions to the entire site since the files that
Frontpage uses are located in the root.
