Hi,
Occasionally some of our users report they can no long access resources they normally can, and it appears that Identity Awareness has failed.
What we notice is the following output from "adlog a dc":
adlog a dc
Domain controllers:
Domain Name IP Address Events (last hour) Connection state
============================================================================================================
<domain> <ip> 39519 has connection
<domain> <ip> 5939 has connection
<domain> <ip> 0 has connection - warning: 0 events in the last minute
Ignored domain controllers on this gateway:
No ignored domain controllers found.
In the above output, I have rebooted the top two DC's, and only the third has the original problem. I have left that machine in that state so that we can hopefully found out what is going on. The only thing we have found that "fixes" it is to reboot all three DC's in sequence. Then its okay again for a number of months.
I have also tried restarting a number of likely services, such as that below, but that nothing that has made a difference so far. I have also checked for the following events in the "Security" log, and they are there: 4624, 4768, 4769 and 4770
Has anyone else come across this?
We already have a ticket open with our support partner, I'm just looking for some feedback from the community.
