Different behaviour on one Proxmox Network

[sebastian.k.e]

Hello everyone,
we have Proxmox running on a single server.
On the Server are two Windows Server 2019 VM installed.
One VM loses randomly connection to the Gateway while the other vm runns fine.
Also there are random packet losses (ping no response) on both vm.

The two vm have the excate same network hardware configuration.
Drivers are the latest virtio drivers.

No, DNS are Localhost in the second, then goes to the 2nd DNS that match the first one
Did you install the VirtIO drivers?

We found the issue. Network discovery on Windows Server was not activated.
