User-ID Agent, uninstall slows down network logons

Hello,

 

I am not a Network Engineer but am trying to assist the folks running the network at my company. I am in charge of Active Directory. The Network Engineers recently uninstalled the Palo Alto User-ID from two of my Domain Controllers. Since then, we have seen network slow downs randomly, for certain Netlogon connections between Domain Controllers. I have also requested them to re-install the software. It is apparently re-installed, yet I clearly see no users in the logs as having been discovered so I can only believe that something is still not quite right with the setup. Does anyone have anything they can recommend I do next? I am at my wits end and truly believe that somehow the Palo Alto User-ID service was somehow helping to keep our logons working correctly, but the network team is swamped with other work as well. Thanks!

@tandersen,

Ya, that's not how it works. The user-id agent simply reads the event logs, it doesn't listen to the network traffic or anything like that. Uninstalling the agent or re-installing the agent absolutely should have no effect on the speed of your Domain Controllers or Netlogon connections.

If what you say is true... why would we start seeing these messages inundating our event logs on the DCs after uninstalling the User-ID Agent? It can't just be a coincidence. Somehow there must be a correlation?

 

Netlogon has failed an authentication request of account *** domain ***. The request timed out before it could be sent to domain controller **** in domain ***. This is the first failure. If the problem continues, consolidated events will be logged about every 30 minutes. Please see http://support.microsoft.com/kb/2654097 for more information.
