Hello everybody, I recently installed Kaspersky for Windows Server v11 and configured the policy, in KSC, to use KSN, accepting all ksn statement. Now, I got thousands of KSN error, such these: Importance level: Critical Event time: 20/04/2021 11:04:22 User: No data Computer: Description: Error sending the request to KSN. Error code: 0x8000004B. Object name: C:\WINDOWS\SYSWOW64\BCRYPTPRIMITIVES.DLL Importance level: Critical Event time: 20/04/2021 11:04:22 User: No data Computer: Description: Error sending the request to KSN. Verify KSN Proxy settings configuration. Error code: 0x80000500. Object name: C:\WINDOWS\SYSWOW64\RPCRT4.DLL It seems that it’s not possible to send KSN requests. Server and KSC are in the same network, with no firewal between them. Can someone suggest me a possible fix? Bye Fab
