“The RPC server is unavailable” with Microsoft Virtual Machine Converter

When I first tried to perform a physical to virtual migration with the Microsoft Virtual Machine Converter 3.0 – I immediately hit this error message:

After a bit of poking around, I was able to figure out the problem.  Microsoft Virtual Machine Converter use WMI, which is blocked on the Windows Firewall by default.  Once I had allowed WMI through:

Everything started working.

    I hope someone will add this info to the error message in the next release.

    I had that too... easy to fix. But then I got a cryptical error on not having 'Bits' on my Windows 8 machine with Hyper/V, that I tried to copy the machine to. It would be nice if the tool would also support some slower/less efficient transport mechanism like normal network shares.

    Is there any good reason why Microsoft Virtual Machine Converter uses WMI instead of CIM? CIM uses port 5986 and that port is already open.

    I'm getting the System.InvalidOperationException: A task may only be disposed if it is in a completion state (RanToCompletion, Faulted or Canceled). error which was supposed to be fixed back in version 2.1. Any ideas why I would see that?

    hmmm i'm getting the same issue (using the computer name or FQDN), but I've even tried disabling the firewall on both the Hyper-V server and the machine i'm trying to convert... if i use the IP of the "target" machine I get the error "Access has been denied while contacting the computer 10.10.10.111.  Verify that the specified user account has administrative privileges on 10.10.10.111" -- which i do (i've tried using a domain admin account and a local admin account) Thoughts?

    Now that I think about it...could my issue be because the machine I'm trying to convert is a Windows 8.1 system?

    I had this problem and like Bert Huijben the problem with bits, I solve it shutting down my firewall on the host machine (Windows 10 Pro) and installing before another virtual server on 2012 R2 to run the MVMC from there wich I previously avtivate the bits compact server
