How to add a new domain controller to an existing Active Directory domain?
The specific situation is as follows: The company has one forest and domain, and two Active Directory (AD) servers. These two servers communicate and synchronize data. One server is deployed in the local data center, and the other is deployed on Azure Cloud. The forest and domain functional levels are both Windows Server 2008 R2. Both servers are running Windows Server 2016 Standard. Because there are computers running Windows XP and Windows 7 in the domain, upgrading the forest and domain functional levels is not possible. Windows Server 2008 R2 must be retained. The company now needs to add a new AD server on Huawei Cloud and join it to the company's forest and domain. The main questions are: How do I determine which operating system the new server should run? Excluding Windows Server 2016. How should I choose between Windows Server 2019, 2022, and 2025? How do I determine how to allocate CPU, memory, disk, and network resources during system deployment? How to determine which operating system is best suited for running a domain controller without conflicts or incompatibility? What preparations should be made before deploying a new server?
Beyond RC4 for Windows authentication - Question regarding KB5073381
In KB5021131 MS recommends setting the value for DefaultDomainSupportedEncTypes to 0x38, in the new KB 5073381 it's 0x18. This removes the setting that forces "AES Session Keys" which should be fine if Kerberos Tickets can only use AES Encryption. But what about accounts that have RC4 enabled in their msds-supportedEncryptionTypes attribute? They could still use RC4 for Kerberos ticket encryption and would then also fallback to RC4 session ticket encryption. As far as I believe the DefaultDomainSupportedEncTypes was explicitly introduced to avoid this scenario. Or is there now some hard-coded mechanism that always ensures that Session Keys are AES encrypted?
Lots of DNS Server events 5504 on AD DNS server from Cloudflare etc
Hi! I'm getting about 18 events with id 5504 while trying to resolve some DNS names, like fullfiles.xyz. The DNS server is configured to use provider DNS and root hints. I can suppress these messages by disabling root hints or by disabling EDNS0 with dnscmd /config /enablednsprobes 0. I tried to use packet capture on the DC and on the router, and analyzed the results with AI, which answered: "You receive malformed patterns on the WAN interface." Can anybody explain the cause of this problem? Any ideas to fix it? Thanks!
Issues with Group Policy Update (gpupdate)
I am getting an error when I attempt to perform a gpupdate /force on workstations. I have checked the health of the DC's and find no issues. I am going to include a screenshot of the error - hoping someone can guide me as on how to resolve. The system will say to reboot but the policy never seems to run just keeps prompting for reboot.Display On-prem Password Policy on SSPR Page
Hi All We are beginning to rollout SSPR with on-prem writeback. So far so good. Is there a way we can display our on-prem password policy requirements on the SSPR screen? I have seen the MS docs, but can't really make any sense of them so any help would be greatly appreciated. SKForce user to reset password in hybrid
Hi, we work in a hybrid environment at the moment, and it has been discovered that if you are using classic AD and reset a user's password and leave the tick-box saying user must change password at next logon, the password reset works! But, if you were to select the tick-box with the intention to make the user change their password, the password does not get reset and the user never gets asked to reset their password? Also, if you try and reset the user's password on AAD, you get the following error message: Because we cannot force the user to reset their password by AD or AAD, we have to tell the user to do it themselves by the classic Ctrl-Alt-Del method or set their personal password for them over the phone. So, what my question is, is why can I not force the user to change their password from either AD or AAD?
