On your computer, delete %appdata%\mikrotik and try again.

Delete all subfolders from ‘%appdata%\mikrotik\winbox’ but don’t delete ‘winbox.cfg’ file.

HTH,

thanks a lot sir for your replies but still the same i was not able to access winbox, is there any other alternative way?

What happens if you try it from a different computer? Does it work from a different computer?

the same did not work and i can not access any more it beeps only once.

The mikrotik BEEPS when you try to access it from Winbox???
