Insight Discovery and DCOM Hardening June 14, 22

Hi!

 

Can someone tell me, if there is something to do with dcom hardening to keep insight discovery running after june 14, 22?

https://support.microsoft.com/en-us/topic/kb5004442-manage-changes-for-windows-dcom-server-security-feature-bypass-cve-2021-26414-f1400b52-c141-43d2-941e-37ed901c769c

 

At the moment some server log some error messages in windows event viewer. nevertheless some vm hosts can be scanned without some problems.

 

Insight Discovery Server Event Viewer Error: 

DCOM was unable to communicate with the computer x.x.x.x using any of the configured protocols; requested by PID 2af4 (c:\Program Files\Discovery_DEV\Discovery\Discovery.exe).

 

 Scanned VM Host Event Viewer Error:

The server-side authentication level policy does not allow the user xxx (SID) from address x.x.x.x to activate DCOM server. Please raise the activation authentication level at least to RPC_C_AUTHN_LEVEL_PKT_INTEGRITY in client application.

 

best regards,

florian
