I am running one Realtek NIC, on a Windows Server 2019 Datacentre Host machine with 2 virtual machines hanging from this, both running windows server 2019.
Up until recently, there have been no issues with connectivity to the server and we have been running fine. As of an unexpected shutdown on Saturday, we are now able to ping the host with a stable connection, but the guest machines are running
at a 40-60% packet loss continuously.
Steps tried: VMQ Disabled on all machines and adapters Deleting Hyper-V virtual switch Resetting Windows network settings Updating drivers Updating Windows
No settings were changed before it went from working to non-working. Has anyone got any ideas?
