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. |
