How to change accounting period without reboot?

SUGGESTED

I have a client that has to reboot their server every time they change the accounting period because it says multiple users are logged in even though they are not.  I found this other thread but the answer links do not work nor can I search for them.

I am very new to Sage but provide IT support for several clients that use it.  Other clients do not have to do this and this client did not have to do this until they got a new server.  Sage shows only one user logged in but yet then claims that changing accounting period is a single user function and cannot be performed.  Is there something on the server that is not releasing all of the users that log out?  I'm not quite sure if I am wording this right, but it does seem to be a similar issue as the one above.  Thanks!
