RPC Call Failed

What 0x800706BE Means
The 0x800706BE error on the Windows System Errors indicates rpc call failed — the request reached its server but the server-side execution failed. This typically occurs due to the service hosting the called interface crashed or aborted mid-call.
The code 0x800706BE, Win32 error 1726, RPC_S_CALL_FAILED — 'The remote procedure call failed' — describes a delivered call with a dead execution. The endpoint answered, the method was invoked, and the failure happened inside the server process, which separates it from 1722, where nothing was ever reached. Windows Update documentation records a servicing variant: cumulative update packages installed through dism.exe return 0x800706be when the previously installed cumulative update is in a corrupted state.

Trace the crashed host service
Service control manager error events name services that terminated unexpectedly, tying the failed RPC execution to its host process.

A recorded corruption flag distinguishes known store damage from a clean store before deeper servicing analysis begins.

Technical Background
The diagnostic value of 1726 comes from what it excludes. Transport, name resolution, and authentication all succeeded — the call was delivered and accepted. The failure therefore belongs to the server-side implementation: a crash, an unhandled condition, or state so inconsistent that execution could not proceed. Logs on the machine hosting the endpoint carry the real cause; the caller only ever sees the RPC frame's report.
The servicing variant makes the server-side framing concrete: a corrupted prior cumulative update leaves package state that the next servicing call fails to execute, and dism.exe surfaces the RPC failure. The documented recovery operates on the package state rather than the transport, which underlines that the code marked the symptom, not the cause.
Common Causes
- The service hosting the called interface crashed or aborted mid-call
- A corrupt update package left a servicing call failing on execution
- Marshaled arguments crossed a version boundary the server could not interpret
Typical Scenarios
- dism.exe fails to apply a cumulative .msu with 0x800706be after the prior update left damaged package state
- A distributed application's method call aborts because the hosting service process died during execution
- Print or service management operations fail mid-call while the spooler or target service restarts
What to Know
When 1726 appears, move the investigation to the machine that hosts the interface; the caller's logs will contain the report while the cause sits in the server's own event history.
Frequently Asked Questions
Common questions about Windows 0x800706BE error
1726 means the call was delivered and execution failed on the server. 1722 means the endpoint was never reached. The boundary between them is the rendezvous, not the operation itself.
The update documentation describes cumulative packages failing through dism.exe with 0x800706be when the previously installed cumulative update is corrupted; the failing execution is the servicing call against that damaged state.
The event history and application logs of the machine hosting the RPC interface. The reporting caller receives only the RPC-level verdict.
