The Svchost.exe process encounters an access violation error, and services that are running in the Svchost.exe process stop responding in Windows Server 2003

You notice that the Svchost.exe process encounters an access violation error. Additionally, services that are running in the Svchost.exe process stop responding. These services include the following services:

• The Windows Management Instrumentation (WMI) service
• The Server service
• The Workstation service

This problem may occur if invalid input parameters are used in the wbem_wcsicmp() function. When an invalid parameter is received, the wbem_wcsicmp() function in the Repdrvfs.dll file generates an access violation. Then, the Svchost.exe process closes.
