Default Behavior

MRXSMB is a file system driver. In Windows XP it is starting right at Kernel initialization. If the MRXSMB fails to start, the technical information about the error is added to the Event Log. Windows XP startup should proceed, but a message box should be displayed informing the user that the MRxSmb service has failed to start.

Restore Default Startup Configuration for MRXSMB

1. Run the Command Prompt.

The MRxSmb service is using the mrxsmb.sys file that is located in the %WinDir%\system32\DRIVERS folder. If the file is changed, damaged or deleted, you can restore its original version from Windows XP installation media.
