Credential agent crashes LSASS

L1 Bithead

Setup a 2016 RODC so I could use the Credential Agent.

As soon as I try starting the agent as system, the server pops a message that I will be force restarted in 1 minute. It non-gracefully reboots in 1 minute. I tried agent v10 and v9. Perms and settings appear fine afaik, and suppressing a/v didn't help. Palo sent me a suggestion to roll back patches before Jan or even before July of last year but that doesn't seem right, plus Jan is the baseline in my template. Has anyone experienced a similar issue and had any luck?

Thanks for all the replies. This saved me from sinking additional hours into troubleshooting.

I found this via a link in the paloaltonetworks subreddit, and was subjected to the couple of hours trying to figure out what was going on.  Luckily, I knew about the botched MS patches that caused bootloops, so uninstalling the patch tipped me off.  I then noticed that the cred agent was not connected properly to the FW, so I disabled the service and the server was stable.  As soon as I started it, I got the message that the server was going to reboot in one minute.  It doesn't even cleanly shutdown, it acts like issuing a reset in VMware.


The last patches that seem to work are December 2021.  Since our users continue to fail phishing test emails, I'll keep the Dec 2021 patches on the RODC for now until we get a fix.  I did open a case and recommended others do as well so it receives some priority.

Thanks for the reply and sorry I didn't reply faster on that thread. Hope this helps gain visibility.

I wish...  I put in a S2 ticket last Wed, the 16th.  I did not even have my case assigned until the 18th.  Way behind on the SLA for a S2.  The current workaround is to reduce the security of the RODC, or disable the Cred agent.  I hope PAN fixes support.  Certainly a good problem to have (many new customers needing support), but not good for those of us paying for premium support, and not receiving it.
