I am having Pan-OS integarted user Id

[PavanT]

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

@echahine ,

The Problem we are having  is on the user computers,

If you go to Event viewer --> Windows Logs --> System and look for events related to 10036

We are having the authentication error 10036 when using WMI, and we can't solve it. What we're trying to do now is to switch to WinRM-HTTP, its not even connecting to the AD server in the first place.

In order to use WinRM-HTTP, you need to make sure your PA service account in AD has been added to the "Remote Management Users" group. You also have to configure a Kerberos Server Profile on the device tab in the PA. Just create a new Kerberos profile, and add the FQDN of all of your domain controllers to it. Once that is done, you have to apply that Kerberos Server Profile by clicking the 'gear' icon in the Palo Alto Networks User-ID Agent Setup area under Device > User Identification. (select it using the drop-down) Once you commit those changes, your DCs under Server Monitoring should show "Connected" instead of "Connection Refused".

Hey I have the same error, I made the solution that palo alto sends but have no luck, i get that error, could you manage to resolve the issue???

Hey, to the people having issues with Kerberos.
Step 6 indicates RC4 is not a supported cipher.  Have you confirmed your Windows Server is no longer defaulting to RC4?
If someone could test and update the thread that would help the rest.
