Server 2025 Security Baseline breaks Failover Cluster
Hello everyone, while testing the Server 2025 Security Baseline with our Hyper-V Hosts in a Failover Cluster, we noticed the Cluster Service (ClusSvc) was unable to start correctly. It failed with Event 7024 - "A specified authentication package is unknown". From testing and the event logs, we noticed that the .dll file "CLUSAUTHMGR.DLL" was unable to load. After setting "Allow Custom SSPs and APs to be loaded into LSASS" to "Disabled", we were able to start the service again. I assume that the cluster auth manager .dll is not recognized as a trusted Microsoft SSP/AP and therefore blocked as "custom" when enabling this setting. Has anyone tested this using Hyper-V clusters and/or made similar observations? (P.S.: Before debugging, we should have googled, since apparently we are not the only one to have this issue: Failover Cluster Service won’t start on Server 2025 | Jigsolving)Windows 10/11 22h2 Security Baseline missing in Intune
Hi, can you please enlighten when the Windows 10/11 Security Baseline will be updated to 22H2? The current baseline is of November 2021, I am sure that there are new recommedations in the new baseline ( Windows 10, version 22H2 Security baseline - Microsoft Community Hub ) that would be helpful while managing Windows in a more modern way. As an example, currently missing the 22H2 option "Allow Administrator account lockout" to manage it without the need of a GPO.
Question Regarding Server 2022 Domain & Controller MSCT baselines
I have a basic 'Newbie' question regarding the MSCT baselines. I see the GPO for 'MSFT Windows Server 2022 - Domain Controller' and also 'MSFT Windows Server 2022 - Member Server'. I just want to confirm that we should only apply the 'MSFT Windows Server 2022 - Domain Controller' policies to our DC's, and not the Member Server policies as well. While this seems obvious, I just want to make sure.Security Baselines for Linux
Currently only Windows OS is in scope of the Security Baseline assessments. Are there any plans to expand it for Linux (RedHat) as well? I mean our organization has deployed Defender on Linux, so it might be possible Microsoft will support this on Linux OS'es as well. Thanks, DragiYour connection isn't private on edge after hardening plus no home page
Hi, We are in the process of setting up a policy for organizational users using Edge and GPO. We have had a few hickups, two of which I would be happy for assistance with fixing. It's important that all the fixes are via the GPO settings (ADMX as of build 101 of Edge). The first issue is that when the browser starts, we want it to open to our organizational portal, but it opens to "edge://newtab". We managed to set the home page (when you click the home icon) to our portal, but can't figure out how to get Edge to always open with our portal as the main page. The second issue is even more problematic. On some external web sites, even those you would not expect to get it, we get a "Your connection isn't private" message (when trying to browse to "www.google.com" for example. and the internal error is "NET::ERR_CERT_NO_REVOCATION_MECHANISM" We don't have this issue with IE or chrome to the same websites on the same ws's. And we don't have this issue with internal websites. Anyone have any idea why this is happening only on Edge and what the parameter that could be causing this ? Again, it does not happen on all web sites. Some web sites that give this error allow us to move forwards, while others like google, won't even allow that. Would appreciate any help. Mike
[Updates] GPOs Configure Automatic Updates vs. Specify deadlines for automatic updates and restarts
Dear all, we have about 500 Windows servers in our Standalone WSUS environment. I would like to change local GPOs for the (new) non-AD-members, so the compliance related to Windows Updates is improving. Mostly we are using GPO Cofigure Automatic Updates with AU options 4 (schedule the install) as of today. As far as I know, the new GPO “Specify deadlines for automatic updates and restarts” ignores the Configure Automatic Updates GPO with all the AU options (See https://learn.microsoft.com/en-us/windows/deployment/update/wufb-compliancedeadlines), so they can not be combined together. Question 1: Is it true? Do you have some up-to-date information about that? Reading through the update baselines https://www.microsoft.com/en-us/download/details.aspx?id=101056, as far as I can see, the Configure Automatic Updates GPO will be not supported in the future and some related GPO settings are not even recommended due to this reason because they might not work as intended. Question 2: Is it true? Do you have some up-to-date information about that what is still supported? Question 3: Do you know a deadline to deprecate the Configure Automatic Update GPO by Microsoft? (We are planning to have some scheduler settings to begin the installation of Windows Updates and as I can see, “Specify deadlines for automatic updates and restarts” can not do that (it can only schedule the restart) and Configure Automatic Update GPO seems to be moved out from support slowly.) I also checked this material but could not find a focused material for Windows Updates only, especially for servers: https://www.microsoft.com/en-us/download/details.aspx?id=55319 Question 4: Do you have where to find such a material for Windows Updates only or who to ask for them? (Mostly for Windows Server 2016, 2019 and 2022). Many thanks upfront for your answers.
Security Baselines not seeing devices in device groups
I'm trying to test security baseline assessments but the profiles I set will not recognise any device groups as having devices in them. Listing the devices separately, adding tags to the devices and creating new groups with the same devices doesn't work either.
Exploit Prevention Blocking EXE files
My environment is having an issue where exe files are being blocked when executed via a remote share. It appears Exploit Prevention is blocking but it does not happen for every user. I have placed an exclusion using Set-ProcessMitigation -Name filename.exe -Disable BlockRemoteImageLoads and the issues still persist. We do not use Defender for Endpoint as a solution and are not managing Exploit Guard policy via GPO, SCCM, or InTune. Also I have verified the process mitigation is disabled using PowerShell. ImageLoad: BlockRemoteImageLoads : OFF AuditRemoteImageLoads : NOTSET Override BlockRemoteImages : False BlockLowLabelImageLoads : OFF AuditLowLabelImageLoads : NOTSET Override BlockLowLabel : False PreferSystem32 : NOTSET AuditPreferSystem32 : NOTSET Override PreferSystem32 : False This randomly started a few days ago and I'm at a loss for how to move forward and why this occured all the sudden.
MDM Security Baseline in "Conflict" (Tamper Protection blob)
Hi All, I am attempting to implement the security baseline via Endpoint Manager. I have configured a baseline profile and targeted a small group of 4 users. The dashboard shows that all 4 users have received the baseline, but are in conflict. When I check the profile settings, the setting in conflict is called "Tamper Protection Blob". I have done some searching and can't find what exactly that is or how to resolve. Any insight would be awesome!
