Default Behavior

Server SMB Driver is a file system driver. In Windows 7 it won't be started if the user doesn't start it. If Server SMB Driver 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 srv2 service is not running because of the error.


Server SMB Driver is unable to start, if the Srvnet service is stopped or disabled.

If Server SMB Driver is stopped, the Server SMB Driver service fails to start and initialize.

Restore Default Startup Configuration of Server SMB Driver

Before you begin doing this, make sure that all the services on which Server SMB Driver 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 command below, paste it into the command window and press ENTER:

sc config srv2 start= demand

3. Close the command window and restart the computer.

The srv2 service is using the srv2.sys file that is located in the C:\Windows\System32\DRIVERS directory. If the file is removed or corrupted, read this article to restore its original version from Windows 7 installation media.
