A couple times over the last week, one of my ISE nodes has become unjoined from AD. Does anyone know what could cause this? Running 2.4.0357.
Thanks.

I've seen servers which are down appear under External ID sources as Not Jointed, until they were brought back up.
Any chance the servers which were "disjoined" were down or inaccessible during that time?

I would also check with the AD team to see if the machine account was deleted, moved, or disabled. I have had this happen in the past.

Hi,
Please work with the TAC to troubleshoot why this is occuring.

This is possible, except it happened last night when the PSN was not rebooted or brought down. I can double check though to see if something did happen to it.

Yeah, sometimes the alarms don't quite match up with WHY it's happening.
NMS systems usually have something called root-cause-analysis to only bring up an alarm for the exact reason something happened and not other things which derived from that event. Hopefully ISE will do so in the future.
