But before I talk about the specific RPC errors and solutions, let’s get a solid grounding in RPC terminology.command can validate DNS health of domain controllers that run Windows 2000 Server (SP3 or later), Windows Server 2003, Windows Server 2008, and Windows Server 2008 R2.If you’ve worked with Windows server platforms over the years, chances are you’ve seen remote procedure call (RPC) errors at one time or another. This condition may be caused by a DNS lookup problem.RPC itself has no special insight into failures but attempts to map lower layer protocol failures into an error at the RPC layer.
