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:
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.
|0||RPC_C_AUTHN_LEVEL_DEFAULT||Same as RPC_C_AUTHN_LEVEL_CONNECT|
|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.|
