Knowledge Base FAQ Item #7250060

Q7250060: We've raised the authentication level to require RPC_C_AUTHN_LEVEL_PKT_INTEGRITY on all of our Windows servers. Is ActiveXperts able to handle it? We're using WMI through DCOM.

By default, ActiveXperts uses the RPC_C_AUTHN_LEVEL_DEFAULT level to connect to remote Windows Servers. This will not suffice for servers that require RPC_C_AUTHN_LEVEL_PKT_INTEGRITY authentication.
You need to change the following registry entry:

HKLM\Software\ActiveXperts\Network Monitor\Server\DCOM\AuthenticationLevel

and set the value to 5, which means: RPC_C_AUTHN_LEVEL_PKT_INTEGRITY
This requires a restart of the 'ActiveXperts Network Monitor Engine' service!

Please note that this requires ActiveXperts Network Monitor v.2022 build 880.2103 or higher.

Value	Name	Meaning
0	RPC_C_AUTHN_LEVEL_DEFAULT	Same as RPC_C_AUTHN_LEVEL_CONNECT
1	RPC_C_AUTHN_LEVEL_NONE	No authentication.
2	RPC_C_AUTHN_LEVEL_CONNECT	Authenticates the credentials of the client and server.
3	RPC_C_AUTHN_LEVEL_CALL	Same as RPC_C_AUTHN_LEVEL_PKT.
4	RPC_C_AUTHN_LEVEL_PKT	Same as RPC_C_AUTHN_LEVEL_CONNECT but also prevents replay attacks.
5	RPC_C_AUTHN_LEVEL_PKT_INTEGRITY	Same as RPC_C_AUTHN_LEVEL_PKT but also verifies that none of the data transferred between the client and server has been modified.
6	RPC_C_AUTHN_LEVEL_PKT_PRIVACY	Same as RPC_C_AUTHN_LEVEL_PKT_INTEGRITY but also ensures that the data transferred can only be seen unencrypted by the client and the server.
