This is issue is not what I have but seems similar so I'll post here.  I have QB Pro 2020 company file on a PC running Windows 10 Pro using as a 'data server'.  I've set the QB folder to FULL SHARE for Everyone plus at setup I ran the QB Database Server Manager and identified/shared QB files in the stored location.  Now I have 2 workstations that access and yes, we have multi-user licenses.  At the start of each day, one user can log in but it's in single user and when changing to multi user, we get error code H202.  So - I run the QB Database Server Manager on the Data server again and it let's us switch to multi-user.  Works the rest of the day.  Problem.  At the start of each day, we're right back to single user and when changing to multi receiving error code H202 and I have to run the QB Database Server Manager again.  We can make it work but it's a pain having to do this every day.  Anyone have any insight on this unique issue?  Thank you in advance!
