Active Directory Schema Attributes vs Version
Hi all, i'm searching documentations about the attributes used in active directory schema based on its version. My versions range is from "Windows 2008 R2" (v47) to "Windows 2019" (v88). The target of my search is a document/wiki that i can use to check if an attribute exist in my versions range, or, if the usage change in some versions, to prevent exception when a software try to access to it. At the moment, i find only this wiki: https://docs.microsoft.com/en-us/windows/win32/adschema/attributes-all Here i can find all attributes vs schema version and the related information (data type, name, access, etc), but seems not cover the newer schema versions. For example, if i want to check the attribute "department", i can go to the detailed description: https://docs.microsoft.com/en-us/windows/win32/adschema/a-department an see the implementation in older versions (typically the newer is windows server 2012). Exist a list that include newer versions (from windows server 2012 r2 to 2019)? Thanks for any info Stefano
Windows Server 2019 Backup Stopped working
Hi I have a Windows Server 2019 Standard that Windows Server 2019 Backup Stopped working. Worked great for over a year. Here is error : The backup operation that started at '2021-06-13T03:30:22.766521300Z' has failed with following error code '0x8078014D' (There was a failure in updating the backup for deleted items.). Please review the event details for a solution, and then rerun the backup operation once the issue is resolved. I also got an error with invalid option . I am backing up one Folder to a NAS. ioSafe running Synology OS. As a side note : I have a VM server running on this server that is backing up 2 folders to same NAS. Same issue. What I have tried. 1. Freed up space on NAS. 2. On NAS resetup folders backed up to. Made sure folders for Physical Backup and VM have correct permission and NAS user with permission to do the job. 3. Uninstalled Windows server Backup and reinstalled. 4. Re Setup Backup Jobs. 5. Server updates are done monthly and I think NAS OS is up to date. Any Ideas? Thanks you very much in advance! Dexter SoutherlandSetting up MFA for RD Web Access and RD Web Client using ADFS
All servers in our Remote Desktop Gateway (RDG) environment are running Windows Server 2022 (Datacenter and Standard). The RDG environment is fully operational. Users can successfully authenticate to RD Web Access and the RD Web Client, and all published folders and servers are visible as expected. Most servers are configured for direct access, with a few configured as Session Hosts. Overall, everything is functioning correctly except the MFA. Based on my research into integrating ADFS MFA with RD Web Access / RD Web Client, it appears that MFA is only triggered when authentication flows through Web Application Proxy (WAP). Question: To support MFA for internal users without exposing RD Web externally, I’m considering creating a separate WAP cluster dedicated to internal traffic that would proxy authentication requests to the ADFS servers and trigger MFA. Since I’m still building familiarity with WAP and ADFS, is it supported for ADFS to work with two WAP clusters one handling internal traffic and another handling external traffic against the same ADFS farm? -Larry
Windows Backup taking waaaaay to long
While I'm not a heavy user of these MS forums I have had to resort to them from time to time over the last 15-20 years. Yet I still can't figure out the organizational structure and it seems I can never find the right forum for my query. Almost every time my post gets moved to the correct forum or message board, or someone gives me a link directly to it. I expect it to be no different this time, and I'm perfectly fine with that. So here we go. I have Windows Server 2025 installed as a VM using MS's built-in Hyper-V on a Server 2025 computer. the VM is set up as a DC and all that stuff functions exactly as it should. However, doing the backup has suddenly gone from taking anywhere from 2 hours to a max that comes close to but has never exceeded four hours. Obviously, it depends on how much there is to actually back up. I've already gone through the troubleshooting tips to do things like checking the VSS settings and a bit of other stuff I can't exactly recall at the moment. I have an external physical 1TB usb hard drive attached to the physical computer and then it's attached as a drive to the Server 2025 VM and shows up in computer management/disk manager ad Disk 1, as it should. I have the VM set up to use this Disk 1 as the backup disk with the Windows Server Backup program. Some things I note and add here in case it matters. - The size of the VM disk for this Server 2025 VM is 500GB and the partition size of Drive C shows as 498.91GB with the remaining shown as 100MB for the EFI system partion and 1001MB for the recovery partition. - When backup starts, a new disk labeled Disk 2 appears in the disk management window on the VM and I note it's the same size as Drive C on the VM at 498.91GB. I'm wondering if this has anything to do with why my backups suddenly went from taking a max of 4 hours to as long as 20 hours to complete. Where is this virtual disk created? I looked on the VM host machine in the C:\programdata\microsoft\windows\Virtual Hard Disks directory, and it's not there. It's not on the VM machine because the virtual hard disk directory doesn't exist in that same location on the VM. THe host machine itself has a 2TB hard drive in it with 993GB of free space. Any advice or suggestions here? I have no idea why backups went from 2-4 hours to taking 20 hours or more to complete. Thanks for any help, advice or suggestions anyone can offer here. -Carl
SMB over QUIC stops working when enable Cert based Access Control
Trying to test out SMB over QUIC so can eliminate need for vpn. When setting "Set-SmbServerCertificateMapping -RequireClientAuthentication $true" (enabling Access Control) client can no longer connect. "System error 67 has occurred. The network name cannot be found." which seems like a generic error. It works without Access Control enabled. I have: Created a GoDaddy public cert for the Windows 2025 server, and installed it on the Windows 2025 server, used Powershell to make SMB Server Certificate mapping. Used Intune Cloud PKI to create SCEP profile with Client Authentication EKU and pushed it out to test client. (This is also first time using Cloud PKI) Exported Intune Cloud PKI root and issuer CA certs and installed on the Windows 2025 server to Trusted Root and Intermediary Cert Authorities Grant-SmbClientAccessToServer with the Intune PKI issuer certificate. The client is a Entra Only Windows 11 pc. I've read the Access Control doc many times. Added/removed/re-added config over 5x. Obviously I'm missing something but I cannot figure out what. Is Goddady Cert not correct? Intune Cloud PKI cert not correct? something else? I've looked at it ad nauseum in packet capture, but since tls 1.3, handshake is mostly encrypted. I've scoured Event Viewer, but nothing stood out. Any help greatly appreciated.

Hi, We have a HyperV host in a Windows Server 2016 STD with 3 VM Servers Domain Controller (Windows Server 2019) APP Server (Windows Server 2019) DB Server (Sequel) (Windows Server 2016) The host have 4 TB GB HHD 128 GB RAM 2 Processors 2.20GHz We used Veeam backup tool for backups. Suddenly with every backup run, HyperV creates a Veeam recovery Checkpoint. The free disk space of the disk is shrinking considerably. We also noticed that when every Veeam recovery point is created it creates a duplicate of the AVHDX, MRT and RCT files in the Virtual Hard Disks folder. I disabled the Veeam backup jobs until it can be fixed, because if we get out of disk space the VM Servers will not startup. NOTE: This are the production Servers and no other environment for test exists. Hope you can help me thorough this issue.Hyper-V Cluster Failover Event viewer log showing SMB traffic connect to quorum disk network share
Hi, To tweak my SIEM, I need to correlate smb network traffic between Hyper-V servers and witness disk stored on a network share on another server. I'm searching a log who tell me the Hyper-V is connecting to the witness disk (on network shared drive) for doing something ... probably I will be able to correlate and put exception when this happens and the SMB traffic between Hyper-V and the other server to stop always receive this alert. Any cues would be appreciated! ThanksError while running New-VHD cmdlet on Windows Server 2019
Hi, I am trying to create an empty .vhd file using the PowerShell cmdlet New-VHD on Windows Server 2019 virtual machine hosted on Hyper-V. I am seeing the attached error while running the cmdlet: I suspected that it could be related to Hyper-V role on the machine. But, it seems to be all good. Here is the screenshot of what I see on my machine. Strangely I don't see the Hyper-V Services feature on the Windows Server 2019 VM that I am working on. I see Hyper-V Services feature on other VMs on the same Hyper-V for example Windows 10 VM. Any help here will be greatly appreciated. Thanks, Yojana
