I looked at the ldb file in a hex editor, it was 60 bytes long and contained the computer name and "Admin". I could change them and save ok. So I zeroed everything out so it can't work anymore, but still won't delete.
I don't think anybody knows exactly how an ldb file works. Each block is 64 bytes long, not 60 bytes, so there can be 16 blocks in 1k, and 256 blocks in 16k. The size cannot/will not exceed 16K, so there is a maximum of 356 users. Each block is a connection. However, I don't think closed connections get deleted from this file, it's just that the unused blocks can be re-used. I think that's how it works. That's why it's very hard to use the ldb file to identify active users. They will all show Admin, as access no longer allows users to connect to a database as anything else. (there used to a permissions scheme within access). If you only have one block in the ldb file with data, that will surely identify the computer name using the database, but it may well be your own.
