Hi,
We have a server running Windows Server 2019 Standard with Hyper-V. The machine contains 4 Intel X722 LAN ports (on a single card) in a LAN team, functioning as a Virtual Switch. Also the machine contains 2 Intel i350 LAN ports, forming a team for LAN access as well.
Multiple guest OSes are running on this HV host, all of them being Server 2019. All guests experience issues visiting secure websites, sometimes with downloading, have a lot of certificate related issues, ... Some web sites can't be visited at all.
When visiting these from the HV host, everything is fine although it's the same OS.
Earlier we had issues reaching all servers (host and guests) using Teamviewer, but this was solved after applying the fix as mentioned in https://forums.lenovo.com/t5/ThinkSystem/SR630-amp-Intel-X722-issue-with-Windows-Server-2019/m-p/4442619#M867
At this point we have very good performance on our guests but suffer from issues with about anything that smells like using certificates, https traffic, ... For example the Belgian website waterinfo.be is not reacheable from within a guest, but is visited fine from the host.
Time and date settings are OK, all in sync with the domain controller (one of the guests), apps run fine, documents open without issues, SQL Server running nicely and fast ...
We're at the end of our inspiration and hope to get some new here :-)
Thanks
K.
