Hello
Thanks for your answer.
I can confirm it still works even though it fill up the system log.
However, I found the same article than you, and according to these and my understanding, it seems a later update (early 2022) will block connections with a level lower than RPC_C_AUTHN_LEVEL_PKT_INTEGRITY – which seems to be a real problem for us.
Hope someone will catch our call with wmic source code.
