In my environment, few internal devoloped applications are configured to get user and other details from active directory. So they frequently contacts AD to get user details.
Recently, one of the dev team complaned that, they occationally facing problems while connecting to active directory through their application. It was working perfectly earlier but this problem araised recently. They are getting a JAVA exception "ERR_SSN_SRVC/Connection refused" which means that Domain controller is refusing the connections. Upon checking, I came across the below error but resolved it by creating MaxfreeConnections/MinFreeconnections.
"The server was unable to find a free connection 164 times in the last 60 seconds. This indicates a spike in network traffic. If this is happening frequently, you should consider increasing the minimum number of free connections to add headroom. To do that, modify the MinFreeConnections and MaxFreeConnections for the LanmanServer in the registry."
Ever after doing the above, my dev team is still facing the problems and I am not seeing any errors in event viewer except the below.
Any one has idea what does this error means and how can I rectify this? Again, I am not sure if this is the real culprit, let me know if you have any best menthod to isolate the problem.
