- Access Violation in Remote Procedure Call Server Service (Svchost.exe)
An access violation occurs in the Remote Procedure Call Server Service (RPCSS, or Svchost.exe).
- Memory Leak in Svchost.exe
You may encounter a memory leak in the Remote Procedure Call Server Service (RPCSS, or Svchost.exe). RPCSS makes
synchronous calls to track object identifiers (OIDs) for clients as part of the Distributed Component
Object Model (DCOM) pinging mechanism. During this process, RPCSS acquires a handle and memory, which are not released
if these clients are not pumping window messages efficiently. This causes a handle and memory resource leak in the
- "Access Violation" Error Message in Svchost.exe When a Wireless Client Is Being Authenticated
When you are trying to authenticate a wireless client, you may receive an "access violation" error message in Svchost.exe. This means that the Svchost.exe process terminates. (Svchost.exe runs the Remote Access Connection Manager service.) This problem may occur when the following conditions are true:

- A description of Svchost.exe in Windows XP
The Svchost.exe file is located in the %SystemRoot%\System32 folder. At startup, Svchost.exe checks the services
part of the registry to construct a list of services that it must load. Multiple instances of Svchost.exe can run
at the same time. Each Svchost.exe session can contain a grouping of services. Therefore, separate services can
run, depending on how and where Svchost.exe is started. This grouping of services permits better control and easier
- Description of Svchost.exe in Windows 2000
Svchost.exe is a generic host process name for services that are run from dynamic-link libraries (DLLs). The Svchost.exe
file is located in the %SystemRoot%\System32 folder. At startup, Svchost.exe checks the services portion of the registry
to construct a list of services that it needs to load. There can be multiple instances of Svchost.exe running at the same
time. Each Svchost.exe session can contain a grouping of services, so that separate services can be run depending on how
and where Svchost.exe is started. This allows for better control and debugging.
