Spark has worked just fine for the last couple years. However, in the past month there have been days when after logging on to the network, Spark will open but not automatically log you in. Instead you get a message “Invalid User Name.” We have integrated Active Directory with it. This will occur for all users. If I reboot the Spark server then all of a sudden Spark is populated with user accounts normally.
Any idea on how I can resolve this? I’ve looked through services and everything seems fine.
