We are having similar problems.  If we switch to single user mode we can't switch back to multi user mode until it is done on the server.  Which this requires an IT person to run the file dr... And sometimes it takes them an entire day to get back to us because they have the server locked down...  

We are wanting to send pay stubs out by email but that requires to switch to single user mode every time.  We have 4 companies and do payroll every week.

There has to be a solution of not getting locked out of the computer when swithcing to single user mode????

Thanks!
