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: User Computer: Computer
Privileged Service Called:
Server: NT Local Security Authority / Authentication Service
Primary User Name: SYSTEM
Primary Domain: NT AUTHORITY
Primary Logon ID: (0x0,0x3E7)
Client User Name: User
Client Domain: Domain
Client Logon ID: (0x0,0x1234)
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.

This problem was first observed in connecting to Microsoft SQL Server 6.5 with ISQL/W by using Multi-protocol as a transport. Failure auditing of "User of User Rights" must be active to receive this Security Audit event.
