Domain Controller showing network connection as Public
Notice for quite awhile now with the vnext server builds that when you promote it to domain controller it shows the network connections as public or private instead of DomainAuthenticated. Is there a networking piece that I am missing that needs to be configured
VMXnet3 Server 2025 performance issues
Had an odd one crop up today. I updated my Server 2025 template to the 26063.1 release and then sysprepped it. Converted it back to a new VM and network performance was .25 Mbps down. Both on my local lan and on the internet. I removed the VMXnet3 and put in an E1000 and performance was exactly as expected. I shut the VM down, removed the E1000 put in a new network with vmxnet3 and again got horrible performance. I have not seen this with other deployments of 2025 earlier builds.

What's New Rack Level Nested Mirror (RLNM) for S2D Campus Cluster Rack Level Nested Mirror (RLNM) for S2D Campus Cluster enables customers to meet NIS2 two data room requirements for their factories by providing fast and resilient storage using Storage Spaces Direct (S2D). For S2D Campus Cluster, we recommend using all-flash storage (SSD or NVMe drives), all capacity (no cache drives), and RDMA NICs (iWARP, RoCE, or InfiniBand). Note: Rack fault domains must be created on the cluster in order to use this feature – a new cluster must be created: #Create a test cluster but do not create storage: New-Cluster -Name TestCluster -Node Node1, Node2, Node3, Node4 -NoStorage #Define the fault domains for the cluster – two nodes are in “Room1” and two nodes are in “Room2”: Set-ClusterFaultDomain -XML @”<Topology><Site Name=”Redmond”><Rack Name=”Room1”><Node Name=”Node1”/><Node Name=”Node2”/></Rack><Rack Name=”Room2”><Node Name=”Node3”/> <Node Name=”Node4”/></Rack></Site></Topology>”@ #Add Storage Spaces Direct (S2D) Storage to the cluster – note that Enable-ClusterS2D cmdlet can also be used: Enable-ClusterStorageSpacesDirect #Check that the Storage Pool’s FaultDomainAwareness property is set to StorageRack: Get-storagepool -FriendlyName <S2DStoragePool> | fl #Create a four-copy volume on the storage pool: New-Volume -FriendlyName “FourCopyVolume” -StoragePoolFriendlyName S2D* -FileSystem CSVFS_ReFS –Size 500GB -PhysicalDiskRedundancy 3 -ProvisioningType Fixed -NumberOfDataCopies 4 –NumberOfColumns 3 #Create a four-copy volume on the storage pool, thinly provisioned: New-Volume -FriendlyName “FourCopyVolume” -StoragePoolFriendlyName S2D* -FileSystem CSVFS_ReFS –Size 500GB -PhysicalDiskRedundancy 3 –ProvisioningType Thin -NumberOfDataCopies 4 –NumberOfColumns 3 Windows Server Flighting is here!!

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.
DNS Server order on DC NICs
DC DNS Settings Hi, I have four domain DCs. What would be the preferred IPv4 'DNS Servers' order on the NICs? DC01 & DC02 are on one 10Gb network and DC03 & DC04 are on another 10GB network. The two networks have a 1Gb link between them. This is what I'm thinking but any advice appreciated. DC01 DC02 DC03 DC04 Loopback DC02 DC01 DC03 DC04 Loopback DC03 DC04 DC01 DC02 Loopback DC04 DC03 DC01 DC02 Loopback[server 25314] External SET Team to Internal after Reboot.
I have created SET Teaming on Windows Server 25314 (actually from a previous build) using External and 3 Intel i350-T4 ports, configured for Hyper-V and external access. New-VMSwitch -Name SETSwitch -NetAdapterName "i350t4_1","i350t4_2","i350t4_3" -AllowManagementOS $true -EnableEmbeddedTeaming $true -EnableIov $true Set-VMSwitchTeam -Name SETSwitch -LoadBalancingAlgorithm Dynamic In that case, the Hyper-V VM and OS can be accessed normally, but when I restart Windows Server, all Adapters disappear from SET Teaming and are changed to the Internal setting, and network access is lost. The above logs were obtained at WPR with Profile in Network. Since the file is large, I will post a link to OneDrive. setTeamingTrouble.etl https://1drv.ms/u/s!AoGvAA_XXMTH-dJ2gkOa6E5hP4QhLg?e=7hPgLQ In addition, if the EnableIov option is set to $false, a BSOD (KMODE_EXCEPTION_HANDLED) will occur after the Switch is created. VMSWITCH.SYS 0x0000007e (0xffffffffc0000005, 0xfffff80643a95c61, 0xffffb28989f2a6d8, 0xffffb28989f29ef0) Addition 2: LBFO Teaming is working properly. I tried to send it through the Feedback Hub and could not get it to work, so I have included it here. Addition 3: Server 25324 LBFO Teaming with New-VMSwitch failed.
