Kaspersky for Windows Server and KSN issues

[fablser]

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

Hello, I did not yet solve this issue. I tried to disable “Forward KSN request to administration server” and set “Access KSN Cloud / private KSN directly over the internet”. But the result is the same.
