I'm having an issue with my one hyper-v cluster. I have 4 Server 2022 hosts, and 1 Server 2025 host. Live migration works INBOUND to the 2025 host, but live migrations fail OUTBOUND from the 2025 host. I have tried everything I can think of to make sure settings are ok. I have tried both setting it to use all networks, and the specific network. I've matched the live migration NIC settings to mirror what the 2022 hosts have. I've made sure the Hyper-V Live Migration settings all match. They use CredSSP and compression. Nothing seems to be working. Is there some really subtle 2025 bug that doesn't allow for live migrations to lower OS version hosts?
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...
Workgroup Failover Cluster backup service account
Hello, We have built a workgroup Hyper-V cluster. Live migration works well when taking a node. But the only account that we can use is the one used at the cluster creation. I found some post about account creating the same user / password on both node and grant cluster full access. But this account gets access denied in the cluster manager. But I would like to have specific account for backup and also a nominative account for administration. I just read Orin Thomas post , but it did not help. Have someone ever be able to use a different local local account to manager a workgroup cluster ? Or to achieve this need, I must stick to AD registered servers. Thanks for any help. Jean Marie
Active Directory Unable to reset user passwords
I am managing a Windows Server 2025 Active Directory environment with client machines. I created a test user and enabled the option “User must change password at next logon.” I then provided a temporary password to the user, expecting them to get the prompt to change it on first login. However, when the user attempts to change the password, they receive the error: “The user must change password before signing in.” My goal is that when I provide a temporary password to a user: They get the prompt to change the password at next logon. When they change it, it should not throw the “user must change password before signing in” error. I need guidance on how to achieve this so users can reset their passwords successfully.Cluster Aware Updating is Failing with Sep 2025 Updates
We have a failover cluster running on Server 2019, providing file shares. We have been using Cluster Aware Updating with no issues for years now. Suddenly with the Sep 2025 updates it's failing. We did replace out WSUS server for Sep updates, and discovered the cluster nodes had the old server IP configured for WSUS, instead of the DNS alias. But even after correcting that and rebooting both nodes, it still fails. The logs for it when it tries to run " Could not initialize internal Windows PowerShell: (RemoteException) Running startup script threw an error: The specified module 'Hyper-V' was not loaded because no valid module file was found in any module directory.." We of course do not have anything HyperV running. I believer the underlying issue is the beginning of that message "Could not initialize internal Windows PowerShell" I have checked that WMI and WRM are running on both nodes. When running a status check within the CAU GUI, it gives all green checks. Nothing has changed, other than that WSUS server update.Clients failed to obtain internet right after DC 01 failover to DC02.
Hi, Recently, our team conducted a Disaster Recovery (DR) exercise where we successfully failed over from DC01 to DC02. The objective was to verify that DC02 could take over Windows services such as DNS, DHCP, and Active Directory (AD) to ensure business continuity. However, after shutting down DC01, we observed the following issues: Clients began losing internet connectivity. DHCP failed to lease addresses to clients. Connectivity on client machines was only restored after running the ipconfig /flushdns command, which forced them to communicate with DC02. Everything when back to normal when we resumed AD01. For additional context, our environment is also using ClearPass as the RADIUS server and has no issue authenticating clients. I would like to seek advice from anyone with expertise in this area: did we overlook any critical steps during or after the failover process?
Problems with file server role in windows failover cluster
I have a windows failover cluster that consist of 3 virtual servers under os windows server 2019 with 2 file server roles on it, so currently I have one server role on each server and one server in reserve. This file server roles have shared disks on each and connection with azure file share through azure file sync version 20.0. Recently I face a problem that for some reason during the work file server role seems to be stuck and partially unresponsive the only solution is to reboot the node that this file server role is currently on. The only prediction of this problem I've been able to find is Event ID:5783 that relates to NETLOGON The session setup to the Windows Domain Controller for the domain is not responsive. Maybe somebody also faced similar problem or may have some ideas what it might be, or how to fix that, I'll be glad to hear about.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.
HyperV 12 on Windows 2025 ready for production?
Fighting with three HyperV servers in a failover cluster. I understand that now you have to use SET teaming and lbfo is no longer supported. I also understand that SET is still quite buggy. I have created three teams with two adapters in each of them, but it confuses me how they appear in "Network and internet > Ethernet" vs "Advanced Network setting. I have set the vEthernets to the static IPs that I need. But the way the NIC shows up seems random... Some of them shows the IP of the vEthenets and they are all set to DHCP Network seems very unstable if I use more than one NIC in a team. As far as I can google, I am not the only one having these issues. SET networking does not work stable if more than 1 NIC - correct? So if one needs an HA setup - how to handle NIC teaming correct? Can HyperV 12 on Windows 2025 be used in a prof. live setup? thx...
