Noob needs help with RDP Services
I am new to Windows server management. I setup a 2019 Server in a VM (Hyper-V). I installed the licenses we got for RDP from MS after installing the Remote Desktop Services. I am getting an error about Remote Desktop Licensing Mode is not configured. Tells me to use Server Manger to specify RD Connection Broker. Either I neglected to install it or configure it, not sure. Articles I find say go to Server Manager -> Remote Desktop Services -> Overview... BUT, that tells me I am logged in with a local account but must use a domain account to manage servers and collections. Again, not using a DC. This server is not part of a domain. We do not run AD internally only AzureAD online. We have 1 program we still run internally and users RDP to it. Should I remove the service and reinstall? What about the licenses I added already? How to I keep them? Any assistance will be greatly appreciated... J
Hyper-V: How do VMs communicate with external?
Simple scenario: VM --> vNIC --> vSwitch (external) --> physNIC --> physSwitch The vNIC assigned to the VM has MAC address aa:aa:aa:aa:aa:aa, the physical NIC (physNIC; the vSwitch of type external is connected to it) has bb:bb:bb:bb:bb:bb. What mechanism ensures that when the VM sends a network packet to the external network (the physical network connected to the physical switch physSwitch), the MAC address of its vNIC (aa:aa:aa:aa:aa:aa) is used, and not the MAC address of the physNIC (bb:bb:bb:bb:bb:bb)? In other words: what makes physSwitch "see" aa:aa:aa:aa:aa:aa when the VM communicates to an external endpoint?PowerShell counterpart for Failover Cluster Manager "Live Migration Settings"
In Failover Cluster Manager, there's "Live Migration Settings" where I can define what cluster networks I want to carry live migration traffic. Even after some research, I cannot find a PowerShell cmdlet that lets me do the same...
RDP connection not possible and RDS-Virtualization role comes back after restart
Hello everyone, I have here an Windows Server 2022 Standard 21H2 (Build 20348.4052) (essentials) with the newest updates. This is the Domain Controller. Hyper-V is installed with one VM. The VM is a terminal server. In the past I have tried to install the terminal server on the Hyper-V Server. To do so I have installed all kind of remotdesktop roles. This was stupid of me. Especially it does not work on a DC. I want to connect as administrator by RDP (mstsc) to the server but it does not work anymore since I have installed all these roles and features. No other users are connected. I can still connect to the VM. In one situation I was able to connect to the server but after entering the password I have received the error 0x808 (0x101) that there is no licence server for remote desktop available. I have now removed all roles related to the terminal server and the rdp which I have installed. But I can not uninstall RDS-Virtualization. After uninstalling it comes back when I perform a restart. I have already tried Uninstall-WindowsFeature -Name RDS-Virtualization -Remove In the server manager appears a menu item about remote desktop services. But there is written that no connection broker server is in the pool. The submenu server lists my DC. I have found in the eventmanager a error related to the uninstalling process 0x80070057 wrong parameter But I do not have more information. DISM /RestoreHealth and sfc /scannow did not find any problems. I am not using VDI but is maybe the Hyper-V reinstalling the role after the restart? Do I need to uninstall the role to make RDP working again or could be there other reasons? Do you know where I find a detailed log about the problems about uninstalling the role and maybe the installing? Do you have any idea how I can find out more about the problem? Thank you!
Hyper-v Replica Traffic segregation
We have two standalone Windows 2025 Hyper-v Servers. They have been configured with a network team for Management, one for VM traffic and one for replica traffic. We have configured both hosts with self-signed certificate to configure HTTPS replica. The two hosts FQDN are host1.company.com host2.company.com and those names are resolved in the DNS with the management Network IP. To have the replica going through the "replica team" we created on each host's host file two entry like host1.repl.company.com host2.repl.company.com pointing to the replica network IP. The self-signed certificate of each host contains both fqdn ( xxx.company.com, xxx.repl.company.com ) Problem is that when activating a replica for a VM if we chose xxx.repl.company.com as replication partner the process fails with the error that the hosts cannot be contacted, if we use the fqdn company.com it works. To test connectivity we also set the hosts file using the replica network IP for the company.com FQDN and it works. So it's like it doesn't like the FQDN repl.company.,com Any Idea on what the issue might be ? thanksUnable to personalize display in Hyper-V VM
I have two physical servers running Windows Server 2025 Standard Edition, each with Hyper-V installed. On the first 2025 server, I have no issues adjusting video/personalization settings in running virtual machines. On the second server, I created a 2025 domain controller but I am unable to adjust any of the video settings ("remote resolution changes not allowed") even though enhanced sessions are enabled. How can I fix this on the second server? Thanks.
No SET-Switch Team possible on Intel X710 NICs?
Hello, we have lot of servers from different vendors using Intel X710 DA2 network cards. They work fine in standalone and they work fine if we create switch independet teams using Server Manager, Regardless of Dynmic or Hyper-V Port. But sadly we can't use these teams in Server 2025 because have to create SET-Switch Teams instead. But as soon as we create an Hyper-V SET-Switch Team with X710 cards, they have limited to no network communication. They still can communicate with some servers, are slow with some ohters, and can't communicate with some at all. Especially communication to other servers, which also use X710 cards with SET-Switches, is zero. SET-Teams with other cards like E810 work just fine. I've read several times that the X710 cards just wont work with SET, even since Server 2016. But I can't really give up on this, since we would have to replace a lot of them. We have tried to disable a lot of features like VMQ, RSS, RCS... but couln't make it work. Firmware and Drivers are the most recent, but it happens with older versions too. Does anyone have a solution? Thank you!
Active Directory documentation and best practices
Dear all, please, I have to fix a critical situation. I have recovered a DC VM on an old Hyper-V host. This DC is corrupted and seems that it is not working as well. I installed 2 new phisical host (cluster) with Windows Server Datacenter 2025, configured Hyper-V role, networks etc.. Also prepared (out of cluster) 2 new VM Win 2025 and I would like to prepare as new DC01 + DC02. I guess is better to configure the DC on the hosts to grant that the DC role is always available also if the cluster is not running (feel free to correct if I'm wrong, I will appreciate). I need link to video or documents to correctly perform the configuration of the new DC. The old DC are running a Windows Server 2012 R2 standard version. Is it possible to migrate to Windows 2025 datacenter ? Take note that at the end I have to assign to the new DC, the same IP address. thank you very much for your support. BR Alex.
Hyper‑V SET Loop Risk, Asymmetric Paths & Active‑Standby (ALE OXE VM Offline)
Hi everyone, Environment - Windows Server 2025 Hyper‑V - One external virtual switch - Physical NICs combined with Switch Embedded Teaming (SET) - One VM: Alcatel‑Lucent Enterprise OmniPCX Enterprise (OXE) Questions → 1) Loop prevention → 2) Asymmetric traffic → 3) Active‑Standby Problem The OXE VM intermittently becomes unreachable (no ICMP, no SIP). Hyper‑V shows it as “Running,” CPU is low, guest logs are clean. Rebooting the VM or toggling the SET team restores connectivity. Looking for advice on: - Loop‑prevention mechanisms in Hyper‑V SET - How inbound vs outbound flows are balanced - Whether Active‑Standby is possible and how to configure it - Diagnostics to confirm if asymmetric paths or loops are causing the outage Thanks in advance!
