Network problem HPE ProLiant DL380 Gen9

[Antonio3]

Hello I contact you for a technical opinion on the product described below, in practice and for a week that I have problems with the Network of the server, I am attaching images to better describe the problem, in practice on this server on which Windows is installed server 2012 R2, ce a Microsoft Hyper-V, on which there are installed 2 virtual machines, one of the two is accessible from outside in RDS, up to 10 days ago everything worked quietly, while now there are especially when we back up the virtual machine on a dedicated external server, the occurrence of the problem, in the sense that the virtual machine is always on and fully functional but is no longer accessible from the outside and impossible to reach it even locally, so I am forced through ILO to reset the above machine , strange thing that the voice degraded sometimes goes to understand the whole Network sector, but other times the problem exists only as from pictures attached, sure in a kind polite advice, thank you and I offer best regards.

Antonio Gelormini.

P.S. I have done various research on the net but inherent this problem described I did not find any discussion about it, so I decided to write to you, because it is becoming very critical being the server in production.
