Problem
For every database opened for shared use, an .ldb file is created to store computer and security names and to place extended byte range locks. The .ldb file always has the same name and is located in the same folder as the opened database (.mdb).
Resolving The Problem
For every database opened for shared use, an .ldb file is created to store computer and security names and to place extended byte range locks. The .ldb file always has the same name and is located in the same folder as the opened database (.mdb). For example, if you open (for shared use) any of the TDS.mdb Project databases in, then a file called TDS.ldb is automatically created in the same folder. For each person who opens a shared database, the Jet database engine writes an entry in the database's .ldb file. The size of each .ldb entry is 64 bytes. The first 32 bytes contain the computer name. The second 32 bytes contain the security name. The maximum number of concurrent users that the Jet database engine supports is 255; therefore, the .ldb file size is never larger than 16 kilobytes.
