Default Behavior

Server is a Win32 service. In Windows 7 it is starting automatically on the operating system startup. Then the Server service is running as LocalSystem in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Server fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the LanmanServer service is not running because of the error.

Dependencies

4. Restart the computer.

The LanmanServer service is using the srvsvc.dll file that is located in the %WinDir%\system32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
