Cannot Open Service.lck for Writing or Reading

When you attempt to open or list Webs using the FrontPage Server Extensions running on an IIS 3.0 or 4.0 computer, one of the following error messages may occur:

The error is caused by inappropriate permissions on the Service.lck file in the Web you are trying to open.

To resolve this problem, use one of the following methods:

Reset the permissions for the Anonymous Account by doing the following:

The most common cause for permissions problems in FrontPage is manually editing NTFS permissions in Windows NT Explorer. The FrontPage permissions scheme is very specific and applying NTFS permissions manually often causes problems.
