    It's solved!

    The problem was the host 'sap.NWP' doesn't exist in the host file of the system (C:\Windows\system32\drivers\etc\).

    I have added the next entry in the host file: 192.168.X.X sap.NWP

    Thank you for your solution. I was also confused by this problem.

    There is another question: I can't find hostname of our producting system in the host files, while the producting system runs well.
