Default Behavior

Server is a Win32 service. In Windows 10 it is starting automatically when the operating system starts. Then the Server service is running as LocalSystem in a shared process of svchost.exe along with other services. If Server fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the LanmanServer service has failed to start due to the error.

Dependencies

Server cannot be started under any conditions, if the following services are disabled, deleted or working improperly:

While Server is stopped, the Computer Browser service cannot be launched.

Restore Default Startup Configuration for Server

Before you begin doing this, make sure that all the services on which Server depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the commands below, paste them into the command window and press ENTER:

sc config LanmanServer start= auto
sc start LanmanServer

3. Close the command window and 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 10 installation media.
