I have start using Hyper-V on my Microsoft Windows 2012 Server, hosting a 2012 server.

But randomly my virtual machine loosing connections, i see it now when i trying to copy data to it from a old server to this new one.

Both MySQL and FTP connections loosings randomly.

I have searched for this problem and finded that in server 2008 there was some problem and Microsoft got a hotfix for it but that for 2008 server so not for 2012.

I have tried all except the hotfix on this Question: Why are my HyperV VM's randomly losing connectivity?

Anyone has any ideas?
