I can't Turn on network discovery
Hi Why in Advanced sharing settinggs the Turn on network discovery can't save the settings in Windows Server 2019 Preview? Although as an admin I turn it on and save settings, it's again off when I open Advanced sharing settinggs. The second problem is that when I click Choose media streaming optons, I get the message The page failed to load.
Windows Server 2019 warns No Internet Access after AD, DNS and DHCP setup
Hi all. I have a Windows Server 2019 VM (HyperV) where I setup my first DC. I also setup DNS and DHCP on the server. After deploying these, the yellow warning icon appeared on the network icon in the bottom right corner, and it says "No internet access". Indeed, Internet access seems to be working normally. The only issue is the DNS sometimes unable to resolve certain random domains. It seems that unbinding IPv6 from the NIC almost solved this issue, but the warning icon and the No Internet message remains. I tried the troubleshooting tool. It is unable to diagnose the issue, and suggests a network reset. I did it twice, but it did not change anything. I took a dump of the network packets when the diagnostic tool is run, but I see nothing unusual. It finally connects to http://www.microsoft.com:80/ which I think is the normal way to determine if Internet is available. The server responds 200 Ok and some codes. I don't know where to look further. My ipconfig /all: Windows IP Configuration Host Name . . . . . . . . . . . . : SrvApp19 Primary Dns Suffix . . . . . . . : psw.local Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : psw.local Ethernet adapter Ethernet: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Microsoft Hyper-V Network Adapter Physical Address. . . . . . . . . : 00-15-5D-00-78-03 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 10.0.0.112(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 10.0.0.254 DNS Servers . . . . . . . . . . . : 127.0.0.1 NetBIOS over Tcpip. . . . . . . . : Enabled I attach one of the diagnostic reports.

Bypass LBFO Teaming deprecation on Hyper-V and Windows Server 2022
Starting with Windows Server 1903 and 1909, Hyper-V virtual switches on an LBFO-type network adapter cluster are deprecated (see documentation). The technology remains supported, but it will not evolve. It is recommended to create an aggregate of type SET. In practice The SET is a very interesting technology that has some constraints. The interfaces used must have identical characteristics: Manufacturer Model Link speed Configuration Even if these constraints do not seem huge, we are very far from the flexibility of LBFO Teaming. As a reminder, this one has absolutely no constraints. In practice the SET is recommended with network interfaces of 10Gb or more. Therefore, we are very far from the target of the LBFO (use of all integrated boards with motherboard pro, Home Lab, refurbish). If SET cannot be used As of Windows Server 2022, it is not possible to use the Hyper-V Management Console to create a virtual switch with LBFO, as it will prompt an error saying that LBFO have been depreciated. However, it is possible to use PowerShell to create this virtual switch. First, create the Teaming of your network cards using the Server Manager, in my case the teaming will be with LACP mode and Dynamic load balancing mode. Then execute the below PowerShell Command to create the virtual switch based on the teaming created in the previous step: New-VMSwitch -Name "LAN" -NetAdapterName "LINK-AGGREGATION" -AllowNetLbfoTeams $true -AllowManagementOS $true In detail: The virtual switch will be named "LAN" The network adapter cluster teaming is named "LINK-AGGREGATION" The aggregate remains usable to access the Hyper-V host. You will see your network teaming up and running on Hyper-V host. Thats it!
