If the IP works but name does not work, it could be an issue with your DNS.
However, you need to look at the *reason* that is printed at the end of the error message to evaluate why the error occurred in the first place. When error 1601 appears it says *what* happened: “Failed to retrieve WMI info”, and then immediately after that it says *why* it happened. For example, here are just two of the possible ways it might appear:
Error 1601: Failed to retrieve WMI info: Access is denied (Exception from HRESULT: 0x80070005)
OR like this:
Error 1601: Failed to retrieve WMI info. The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)
