BPA Errors: DNS can't resolve GC, Kerberos, PDC Resource Record, etc.
Hello, I've been poking around this for hours now and could use another set of eyes. This server has been the PDC for quite some time but I discovered the last people that managed this place, didn't demote the old 2008R2 server (thankfully it still existed virtualized). So I was able to do a graceful demotion of that and removed it from the domain. I'm now trying to resolve some other errors in that come up in the BPA scan... All reference DNS and I just can't figure this out. I've been beating head against the wall trying to understand what's happening, This is MS Server Standard 2022 only 1 DC and DNS. (yeah I know, don't get me started, but it's a really small office)... Would love some suggestions. Thanks!BenTheITGuyFeb 11, 2025Copper Contributor58Views1like5CommentsWindows Server 2019 and .NET 4.8?
Hello, On a fully updated Windows Server 2019, roles and features allow me to install only .NET 4.7. One of the solution we are using require .NET 4.8 (Adaxes). When I install .NET 4.8 using the installer available here https://support.microsoft.com/en-us/topic/microsoft-net-framework-4-8-offline-installer-for-windows-9d23f658-3b97-68ab-d013-aa3c3e7495e0 It works, I can install Adaxes, but it break ServerManager as well as Azure AD Connect. What's the correct procedure to install .NET 4.8 on Server 2019 without breaking anything else? Thanks a lotYoannFeb 11, 2025Copper Contributor196KViews5likes32CommentsLocal Group Policy

I have a lab with various Servers running Windows Server 2025. Some of them are installed without Desktop Experience, some with. Aside from Desktop Experience, the VMs and the operating are configured the same way using automated setup scripts. I exposed the VirtualizationExtensions for all VMs on the host using Set-VMProcessor -ExposeVirtualizationExtensions $true. Moreover, I configured all VMs to use static memory assignment. However, when I try to install Hyper-V on Windows Servers 2025 with Desktop Experience, I receive the error Hyper-V cannot be installed because virtualization support is not enabled in the BIOS. The issue occurs without any updates installed as well as with KB5050009 (2025-01 Cumulative Update for Microsoft server operating system 24H2 for x64 based Systems) installed. On machines without Desktop Experience, Hyper-V can be installed without any issues. As a side note, on VMs using Windows 11 24H2 on the same host, I can install Hyper-V without any issues.RokoryFeb 11, 2025Brass Contributor204Views0likes4CommentsWindows Server 2025 | Kerberos Local Key Distribution Center (LocalKDC) service fails to start
I have found that this service was disabled before the December update, for some reason it has gone to automatic and cannot be started, maybe this behavior is normal if you are not using this feature. After the January security patch the service still does not start, I think microsoft should report this problem. This happens on a clean installation without any role installed, I know there are many users with this problem. The January patch has not fixed it.mk3Feb 08, 2025Copper Contributor1.1KViews2likes6Commentswof compression not working on Server 2019, compact /exe:lzx
Hi! Got this oddity where it works on some 2019 but not others. It's volumes that support compression. compact /c .\textfile.txt Compressing files in E:\test\ textfile.txt 80510 : 20480 = 3,9 to 1 [OK] Works. But this doesn't compact /c /exe:lzx .\textfile.txt Compressing files in E:\test\ textfile.txt [ERR] textfile.txt: The file system does not support compression. Found another tool that gives a little bit more / other info. https://github.com/wimbrts/WOF_Compress WofCompress.exe /c:lzx /path:textfile.txt Compression using LZX algorithm Error WOF driver missing! Some more info posted as issue at the authors github. https://github.com/wimbrts/WOF_Compress/issues/1 Anyone got a clue why it works on some server and not others?

Hi all, We've been getting curl.exe coming up as a vulnerability in scans. Looks like this was added to Windows, but isn't really kept updated via MS update... seems like a bad practice. Anyway - what's the recommended way to update the curl.exe? Just manually replace the file with the latest version? Are there any potential issues that could arise from doing this? Thanks for any help.SolvedPalmerEldritchFeb 05, 2025Copper Contributor65KViews1like7CommentsTSplus as an alternative to RDS without paying RDS license fees to microsoft
Hello, We are evaluating whether to use TSplus (https://www.terminalserviceplus.eu/) as an alternative to Microsoft RDS/Terminal Server. According to TSplus we can not install or uninstall the RDS role, so we do not use RDS CALs and use TSplus CALs. This way it would not be necessary to pay for Windows Remote Desktop licenses. Is this correct? I can't find any information from Microsoft about it reading documentation. As I see it is correct that using TSPlus without installing Microsoft RDS it would not be necessary to pay Remote Desktop licenses. Could someone confirm me that it is so?colorvivoFeb 05, 2025Copper Contributor23KViews0likes16CommentsWindows Server 2022 Standard - Limitation in RDP sessions with active GPU on Hyper-V DDA?
Hello community, we have a testsetup and try to find out is there any limitation in the number of users when a GPU is installed on a Windows Server 2022 single session host. Our test setup is a 32 Cores CPU AMD Epyc 256GB of RAM 2x Nvidia RTX A5000 2TB NVMe storage Hyper-V GPU DDA to one VM We have created 30 Testuser and set the following groupe policies: Disabled UDP protocol only TCP Disabled WDDM driver Set physical graphics adapter to use for all RDP sessions But currently we get the issue DWM.exe is crashing after the 19 session is opening and all other user 20,21,22,23 can never connect. User which is disconnecting and trying to connect get an error during the start of the RDP session. It makes no difference if 1 or 2 GPU are connected to the VM. But if we check the hardware usage, we have a lot of free resources. Is there any limitation or any idea what we can do? Splitting the VM to different smaller VM is in our case not an option regarding the running software what we need. When we deactivating the setting Set physical graphics adapter to use for all RDP sessions All users can login to server and it seems to be the GPU are working maybee for browser, office etc. but OpenGL, DirectX etc. is not available what is bad. I hope you can support here and explain if there is any settings, limitations etc. Thanks!CijayFeb 04, 2025Copper Contributor847Views0likes1CommentGroup Policy object did not apply because failed error code:0x80070709 The printer name is invalid
Hi Everyone, I have a few AVD pools where we publish an app for users to access. Users report that printers are not being mapped after login. We use GPP user side to map printers and set as default. Many a times we see these events logged: VALUE>The printer name is invalid.</VALUE></PROPERTY>-</INSTANCE> Event ID 4098 is logged in the Application Log: Log Name: Application Source: Group Policy Printers Date: <DateTime> Event ID: 4098 Task Category: (2) Level: Warning Keywords: Classic User: SYSTEM Computer: server.fabrikam.com Description: The user 'HP Printer' preference item in the 'Define Printers {XXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}' Group Policy object did not apply because it failed with error code '0x80070709 The printer name is invalid.' This error was suppressed. For this one I found this KB which is really not helpful since there is no possible solution as the client is a AVD VM and used by many users at the same time.

This error was suppressed. No KB's or posts out there to help with these 2 errors. Really need assistance and printers are not being mapped on first logon, users need to come out of AVD and go back and relaunch the app to see the printers mapped. This is the same case with our internal app or Notepad. Thanks, MDolinhasFeb 04, 2025Brass Contributor801Views0likes2Comments
