On 9/7, our SQL Server Express Database started to report Event ID 17809 "Maximum number of connection (3) has already been reached" . As far as I know, no changes were made to the database/server. The last windows updates were installed on 7/19. The server was rebooted on 7/26 and then not until 9/6.
We ran the SP_Configure query:
sp_configure 'show advanced options', 1
sp_configure 'user connections', 0
If I look in the SQL Server Connection properties, Maximum Num of Server Connections = 0
and Allow Remote Connections is checked and query timeout = 0
Thanks for any help! -j
