About multi-user QuickBooks
This computer is currently set up to host multi-user access to company files.
It may be hosting multi-user access to local files only (those located on this
computer) or local and remote company files (those located
on this computer, as well as those that you open on other computers).
If you stop hosting multi-user access, you will prevent other users from opening
these company files in multi-user mode. If other users are currently working
on company files, you must wait until those users have closed QuickBooks.
