No handler found


In windows hosts i want to check the file.
In nsc.ini file i added the following ,
check_file_w=inject CheckFileSize ShowAll MaxWarn=1024M MaxCrit=4096M “File: C:\WINNT”

when tried the manual check from nagios server using check_nrpe it returns the state as ok .But after configuration in the web console showing status as “UNKNOWN” and status information as “UNKNOWN:No handler found”.

Can anyone help regarding this…

Thanks in advance,
