Record marked as obsolete and not updated for a long time.
The lman file extension is associated with NT Services for Mac, a Microsoft Windows NT Server component that provided file and print sharing for Macintosh clients.
An lman file contains data used by NT Services for Mac and is intended to be managed by that service rather than opened as a standalone document. The format is obsolete because the Windows NT Server service is no longer supported on current systems.
An lman file is not normally opened directly. It was used by NT Services for Mac on a Windows NT Server system, where the service interpreted it as part of its operation.
There is no known general-purpose converter for the lman file format. Because the file contains service data rather than user documents, it cannot normally be converted into a common document or image format.
