DCOM Hardening: Different Versions of Windows
My version is win10 19042.
when i try to execute any wmi command in my domain; (such as; wmic /node:IPADDR computersystem get username )
If server and client versions are the same, command success; (Windows 10 19042)
If server and client versions are different; (Win10 19044, Win10 19042) it gives an error:
The server-side authentication level policy does not allow the user domain\User SID (xxx) 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.
I also created the registry key named "RequireIntegrityActivationAuthenticationLevel" on the remote computer and set its value to 0 but it doesn't affect it and gives the same error.
How to overcome this situation except upgrade all remote computers?
