Hi!

Does this problem exist since the installation of Windows? Did you follow the Windows guest best practices? Please also post
Code:
pveversion -v

Dear Dominic!

Thank you for your help.
We are reinstalled proxmox from v5 to v6 and migrate all VPS, but the problem presist.
We are using MS Server 2016 Standard, with RDP licensing service. I think the problem maybe beetween RDP and NOVNC login. (I guess)
I don't know exactly when started the issue, but once the proxmox drop the network adapter, we restart the MS server, and after a few week, when I realized the problem first (we use RDP). All other Server or Windows VPS still good.

Do you have a similar VM configuration (qm config <vmid>) for the bad VM and the good ones?
 
@aluix12 It is very likely that the community or a staff member will answer your question after some time.

Yes, the configration is totally same .Yesterday I was need reinstall the server, and I lost the newer Windows VPS config's. Therefore I cloned the bad VM's config, and rewrite uuid, mac and other, and working well. This is a Windows Server standard and using rdp licensing, maybe the problem comes from there.

I don't know how RDP licensing works exactly, but if cloning and changing a few configuration parameters works, then I don't think that PVE itself is the problem.
