Thanks for all replies in advance. In monitoring our audit log we are getting the error below. We have 4 different servers running CACHE 2014.1.1 and this is happening on all 4 of them. I have not been able to find what process is trying to logon but it is happening every 30 minutes. We have no user processes that are running so this has to be a CACHE process. Does anyone have an Ideal what could be running to cause this? What kind of trace can I run to determine what process is running it?
