We're trying to demote two domain controllers 2008R2 in a domain ( domx.company.local ) that is part of a forest Company.local We added two new domain controllers into domx.domain.local and tried to demote the two old one.

Any help on solve the issue is appreciatedHow to choose the correct server edition?
Hi, I am new to IT and currently studying for my first helpdesk job. I was following kevtech it support on youtube and he basically guides us to go over 2016 server, and when I asked on a post on linkedin, a lot of people told me that 2022 was very popular nowadays, and I also heard the mentions of server 2025. They recommend that I research this on Chatgpt, the usage of the versions and their differences, however, I also hoped I could get some input with the community experienced with those different versions. So if you have any input or advice, I would highly appreciate it. Thanks in advance.
SRV 2022 WDS - Can't import Realtek NIC Drivers
hello, i'm using windows deployment services (WDS) on my windows server 2022. many clients (windows 10 and windows 11) have a "Realtek PCIe GbE Family Controller" as onboard NIC. if i get the required driver from ex. HP or DELL i can't import it into my WDS server (error code:0xC10408A6). even the driver from the microsoft catalog won't import. normally i would get it from realtek homepage, but this driver won't import either. a friend of mine has a WDS on a windows server 2019. he can import the driver from the realtek homepage an it works fine. what can i do? the error description says that the cause for failed packages includes unsigned x64 driver-package (it's signed), network connectivity (it's fine) and package corruption (but it works on server 2019). my 2022 server has the latest windows updates.
WS2025 - LocalKDC Service Stopped
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 problem occurs in a clean installation without any role installed or configured. If you try to start the service it shows the following error
DNS Server cannot lookup domain AWS
Hi Everyone, I have an issue with the DNS service on Windows Server 2019. I have a CNAME record pointing from an internal domain to a domain hosted on Route53. However, this record frequently returns an 'unknown host' error. My server is already connected to the internet, and the record has a TTL 60. Please help me with this case.
Delete Recovery Partition on a Dynamic Disk?
I have a Server 2022 standard box, and am trying to expand the C: partition to a large size. This is a virtual machine running on underlying ESX 8.0. I added the space to the disk in vmware settings, but it appears I cannot extend the C: partition because there is a recovery partition positioned between C: and the new unallocated space. I have used diskpart in the past to remove the recovery volume in this same situation, but am now greeted with this error when attempting to do so: "Virtual Disk Service error: the operation is not supported by the object." Any help?
Should "Don't be afraid..." be the title for DNS Scavenging in the Windows Server doco?
I was reading about DNS scavenging in Windows Server and AD today (2025-05-18, as a newbie to this topic), and came across the main "Learn / Troubleshoot / Windows / Windows Server / DNS scavenging setup" article here. (https://learn.microsoft.com/en-us/troubleshoot/windows-server/networking/dns-scavenging-setup) The HTML title for this page is "Don't be afraide of DNS scavenging, just be patient - ...". Is that really what you want to go with here? That's a rather more conversational tone than many of the other articles in the Windows Server or Azure documentation. And when displayed in a web browser tab, it's a little inconvenient, because those are truncated on the right, so when you have many tabs or are browsing on something with a small screen like a laptop or tablet, you might get a tab that says just "Don't be afraid of...", which IMHO is less useful for distinguishing tabs than e.g. "DNS scaveng...".
Unable to use preview pane for PDF in File Explorer on Windows Server 2022
It is working locally on our computer. We receive the following: Have made sure the acrobat reader has the functions turned on in the options to preview.

Any suggestions?Windows Server 2016 | Hyper V VM Network Adapter Issue
Hello, we have had an issue for the past week with our Hyper V virtual machines not receiving internet although being connected to an External Hyper Network Switch. Making sure they had internet, we tried switching the NIC correlated with the External Switch and have still had no luck. These systems are crucial to everyday company productivity so we are trying to avoid reinstalling Hyper V at risk of losing functionality with these VMs, an APP and SQL Server, both the VMs are running on Windows Server 2016 along with the domain controller. The computers in the office are having no trouble connecting to the domain controller it is just when, because of the no network connection, they try and connect to these VMs they have no luck. We are getting a new server next week so any help quickly would be appreciated. Thanks!
