Microsoft Entra Connect sync stopped, request upgrade and library not found
Hello, I have the latest (for our company, present on Entra blade) version of Microsoft Entra Connect Sync: 4 days ago I noticed on Synchronization Service Manager that there is no sync of data; I have started the Microsoft Entra Connect Sync and found a big button with "Upgrade" word; I tried to execute the upgrade but when the it arrives to the Connect to Microsoft Entra ID step, I fill with my global administrator account but found a stop error: An error occured while retrieving the Active Directory schema. The error was: Could not load file or assembly 'file:///C:\Program Files\Microsoft Azure AD Sync\Bin\Microsoft.IdentityModel.Clients.ActiveDirectory.dll' or one of its dependencies. The system cannot find the file specified. and when I click again on Next I have the same request of global administrator user and password and the same error. Now, the library is not present but I verified, in a test tenant where I have a working Entra Connect Sync system, that the files is not present even there (and also when I start Microsoft Connect Entra Sync I haven't the upgrade button there); I also tried to repair the installation, but obviously the file is no there. What can I do? Are there other people with the same issue? Any idea is appreciated.
Azure AD Health Failing
I am on the latest version of Azure AD Connect (2.5.79.0)... There are no network/DNS/connectivity issues at our site, it seems to me that Azure AD Health Service is having trouble because the endpoint is experiencing a service issue.. Is anyone else having the same problem with failure alerts/etc? I checked by running "Test-MicrosoftEntraConnectHealthConnectivity -Role SYNC" command, the stack trace throws an undocumented error number and complains of rate limiting issues... smells like the server is being overwhelmed or there are other issues slowing down the endpoint/service with the consequence that connections are piling up causing this error: Connectivity Test Step 1 of 2: Testing dependent service endpoints begins ... AAD CDN connectivity is skipped. Connecting to endpoint https://login.microsoftonline.com Endpoint validation for https://login.microsoftonline.com is Successful.

Standard Operating Procedures in OneNote - Best Method?
Hi, I've been in business for over 18 years, with 6 employees. We have over 300 policies and procedures that have been written and rewritten. They have always been stored on our Sharepoint server in a regular file folder structure that syncs to our computers. Because of it, nobody uses them for they are difficult to find. Sometimes you don't know the name of what you're looking for, other times its an SOP that could be under production or finance. The system has just never worked. I'm currently implementing a system in OneNote. I have it set up where our 9 primary areas are all tabs. There then exists sections for checklists, specific procedures, and then one large 20-30 page manual for that department that discusses in detail everything that needs to be known. An example is in the 23-page Marketing Manual, there are five paragraphs explaining what brand colors are, why they are important, and why we can't stray from them. It then has a few links to reference other documents, one of them is our Branding Sheet that is a Word document, stored inside OneNote. OneNote is also great because it's desktop software that each of our computers has, every single document can be searched at once, you can utilize links to any part that you'd like, you can utilize tags, and you can store the referenced document inside OneNote (so I don't have to deal with somebody changing the file name or somehow breaking the link to the server. I haven't released it yet, but my employees say they would use it if it were easy. As I'm slowly going through and entering the SOPs into OneNote, I'm finding minor issues with my system in OneNote The formatting is VERY limited. So making a great SOP is not as easy as it is in Word Once I have everything in there, I dont think I can get it back out in an editable fashion. I can print the .pdf but it's not like it's a Word document that can be moved around You can't really set permissions on it. I can lock pages, which would work, but I'd prefer permission on different areas Getting everything in there is going to be challenging enough, then I have to go back and link everything. Before I spend too much time organizing these SOPs and copy/pasting them into OneNote, I was hoping that somebody has gone down this road before and can either advise me away from OneNote to another product or offer advice as to why I should keep going down my path. Thanks in advance. Aaron
NgcSet stays NO despite working WHFB setup - RPC 0x800706ba error
Hi everyone, I need help with a Windows Hello for Business certificate trust deployment that's almost working but stuck on the final step. **What's Working:** - Manual certificate enrollment works perfectly: `certreq -enroll -user -config "MyCA.domain.local\MyCA-CA" "MyWHFBTemplate"` - TPM 2.0 is ready, enabled, and functional - All Group Policies applied correctly (computer and user) - CA server healthy, templates published **What's NOT Working:** - `dsregcmd /status` shows `NgcSet : NO` (should be YES) - `NgcSvc` (Microsoft Passport) service is stopped on client - Getting error: "RPC server is unavailable (0x800706ba)" during automatic certificate enrollment - PIN setup fails because NGC containers won't create **The Strange Part:** Manual certificate enrollment works perfectly, but automatic enrollment fails with RPC errors. Both should use the same communication path to the CA. **Environment:** - On-premises certificate trust deployment (no Azure AD) - Domain-joined Windows 11 clients - Windows Server 2019/2022 infrastructure **Questions:** 1. Should NgcSvc start automatically when WHFB policies are applied? 2. Why would manual cert enrollment work but automatic fail with RPC errors? 3. Is there a difference in how system context vs user context accesses the CA? Has anyone seen this specific combination before? Any ideas what could cause this behavior? Thanks for any help!Adding Proxy Addresses in AD Before Tenant-to-Tenant Migration Cutover
We're in the process of migrating users from another M365 tenant into our own, which is synced with on-prem AD. Before the cutover, we'd like to add the proxy addresses from the source tenant to our AD and have them sync to the cloud once the domain is added to our M365 tenant. Would this work as expected, or are there any potential issues to be aware of?Microsoft O365 Auto Login
I want to set up auto-login for the O365 desktop application. When a user logs in to an on-premises AD-joined device, the O365 application should automatically log in with their AAD credentials. I have an AAD subscription, and user sign-in is configured with password hash synchronization. Additionally, I have enabled SSO on the Azure AD Connect application. Please note that the end-user devices are not Azure AD-joined.
