DOCUMENT:Q238185 06-AUG-2002 [winnt] TITLE :Unnecessary Security Failure Audit (Event 577) PRODUCT :Microsoft Windows NT PROD/VER::4.0 OPER/SYS: KEYWORDS:kbenv kberrmsg kbWinNT400PreSP7Fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 4.0 - Microsoft Windows NT Workstation version 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== When you are using a Remote Procedure Call-based (RPC-based) client/server program, the following entry may be logged in the Security event log: Event ID: 577 Source: Security Type: Failure Audit Category: Privilege Use User: Computer: Text: Privileged Service Called: Server: NT Local Security Authority / Authentication Service Service: LsaRegisterLogonProcess() Primary User Name: SYSTEM Primary Domain: NT AUTHORITY Primary Logon ID: (0x0,0x3E7) Client User Name: Client Domain: Client Logon ID: (0x0,0x1234) Privileges: SeTcbPrivilege CAUSE ===== The security audit occurs while the RPC subsystem acquires the user's credentials for authenticated RPC. There are two ways for the code to do this. If the first method does not succeed, the second method is tried. In this case, the first method (calling the local security authority [LSA] directly) does not succeed and generates an Audit Failure entry. Note that this audit does not indicate a security breach; you can safely ignore it.
