For some reason the Agent stopped working on the end user computer. when i checked the event log i came with an error for the id 10036 ( The server-side authentication level policy does not allow the user domain\user SID (X-X-X-XX-XXXXXXXXXX-XXXXXXXXXX-XXXXXXXXX-XXXXX) from address xxx.xxx.xxx.xxx to activate DCOM server. Please raise the activation authentication level at least to RPC_C_AUTHN_LEVEL_PKT_INTEGRITY in client application ).
Can i know how to resolve this issue
A couple months back Microsoft pushed out an update that did some DCOM hardening that you are running into (KB5004442). I'm guessing you or your server team finally got around to patching your servers and enabled the registry key. My guess is that you are using an outdated version of PAN-OS or the User-ID agent, because I don't recall having to do anything about this particular patch and I can't find the advisory that was sent out about it.
We are experiencing the same problem. Just installed Microsoft Patch Tuesday updates on our Domain Controllers. Now getting the Windows Event ID 10036. "The server-side authentication level policy does not allow the user DOMAIN\userid SID () from address <> to activate DCOM server. Please raise the activation authentication level at least to RPC_C_AUTHN_LEVEL_PKT_INTEGRITY in client application." Anyone else out there getting these errors or have a solution? Our Paloalto PA-3050 is current on all updates, running version 9.1.11 of the software.
