Error: "0x80040605 Failed to process a request ... (0x80070721 A security package specific error occurred)".
|Symptoms||When trying to connect to Netwrix Auditor Server (with Netwrix Auditor client or Integration API), you get the following error:
0x80040605 Failed to process a request because the target server is unreachable (0x80070721 A security package specific error occurred).
|Cause||You are trying to contact Netwrix Auditor Server by its IP address while NTLM authentication is disabled through group policy. In this case, Windows cannot resolve server's IP address into a service principal name (SPN) and Kerberos authentication fails.
Review a list of NTLM restricting policies and their settings:
|Resolution||Netwrix recommends enabling NTLM authentication.
If for some reason, you cannot enable NTLM authentication, review the following workaround: contact Netwrix Auditor Server by its computer name. For example, WKSWin12R2, EnterpriseWKS.enterprise.local.
