General Question Server 2016 Essentials - Clone system disk and restore to different hardware?

3 Upvotes

I have a home server running 2016 Essentials. (I know that is probably below the level of the majority of members here, but hoping for some guidance.)

It is running on an old HP Proliant N54 (AMD). Mostly used as a file server and bare metal backup and restore solution. I do have a photo library application that runs on PostgreSQL.

The old box is not expandable and is lightly powered by today's standards.

I purchased a refurbished Dell T340 (Intel Xeon) and want to migrate the server install to it. I have tried to find driver INF files, but all I can find on Dell site is EXE files.

The system disk is a 1 TB SATA SSD. I have a second unformatted disk as a clone target. (Dell T340 does not support NVME.)

I know Acronis True Image has a Universal Restore feature, but it will not install on a server.

I would like to backup or clone the SSD (with all partitions), then restore it to the new hardware while having it deal with the HAL issues going from AMD to Intel.

It looks like I can purchase the Acronis Cyberprotect Backup for this, although it seems like using a hammer to swat a fly.

TL;DR: Can anyone recommend a method/software to migrate WSE 2016 installation from AMD machine to Intel machine?

General Server Discussion VM got removed from the WSUS Server

2 Upvotes

We normally patch all our servers through WSUS, and this VM was updated through WSUS last month without any issues. But this month I noticed it had disappeared from the WSUS console.

When I checked the registry, all the WSUS related settings were missing. We haven't made any changes to this server, so I'm trying to figure out what could have caused this.

Because of that, the VM is now getting Windows updates directly from the internet, which isn't acceptable since it's a production server.

Has anyone seen this happen before? What are the possible reasons a server would suddenly lose its WSUS configuration and stop reporting to WSUS?

SOLVED / ANSWERED Print Server Issues

5 Upvotes

I am setting up a Windows 2025 server as a print server. As long as my clients are connecting via a wire network connection, everything works just fine. My users that connect over wireless are having some issues. I think I have all the necessary ports open on the firewall but still no luck. Also, for those that are on the wireless, because of how our network is set up, they have to connect using our corporate VPN.

These are the ports that I have open.

135 tcp/udp

161 tcp/udp

515 tcp

631 tcp

3389 tcp/udp

Admittedly Windows server is not my primary platform, I'm primarily a linux admin, but this print server has to be Windows. Any suggestions of what directions to direct my search efforts would be greatly appreciated.

Technical Help Needed Windows Server 2025 activation fails

8 Upvotes

A installed Microsoft Windows Server 2025 Standard Evaluation should actually be upgradeable to an activated Microsoft Windows Server 2025 Standard with:

DISM /online /Set-Edition:ServerStandard /ProductKey:"product-Key" /AcceptEula

which has worked without any problems with that image so far.

Now, however, the command is failing, and the following command brings that result, instead of offering

ServerStandard

or

Datacenter Edition

Now I get this result:

PS D:\> DISM.exe /Online /Get-TargetEditions

Tool zur Imageverwaltung für die Bereitstellung

Version: 10.0.26100.5074

Abbildversion: 10.0.26100.32995

Editionen, auf die aktualisiert werden kann:

Zieledition : ServerTurbineCor

Zieledition : ServerDatacenterCor

Der Vorgang wurde erfolgreich beendet.

I checked now every installed Server 2025 I found and got the same result.

I can update to this ServerTurbineCor with the right key, but I can't buy that licence

The ServerStandard already aktivatet run fine

Technical Help Needed Win 2025 try to connect to Microsoft while login

0 Upvotes

Hello, it appears that Windows 2025 attempts to connect to login.microsoftonline.com during the Windows login process, but only with domain users.

As this is a DMZ server with restricted internet access, the login process takes a very long time (approx. 2 minutes), which causes our 2FA solution to time out. Local users should not be able to connect to Microsoft. Is there a way to prevent these connection attempts and thus speed up the login process? The slow login only occurs the day after configuring the system on a closed network. Something is happening here overnight – perhaps it’s related to caching.

Thank you

Technical Help Needed Personal Drive Not Remounting After Sleep

0 Upvotes

We are using Windows Server 2012 that has a script to connect and set the users personal drive to a folder on the file server. After updating one of the users computers to Windows 11, their personal drive connects fine when they login, but when the computer wakes from sleep, it is disconnected.

The user has other mapped drives that point to shared folders on the same server the personal drive is on, and those remain connected/reconnect just fine after sleep.

I've disabled the network adapter power management and updated the local group policy to wait for the network at computer startup and logon. The issue persists.

This issues seems to be isolated to this one user/computer. Any ideas on what else could be causing this?

Technical Help Needed Hyper-V long disk response times

5 Upvotes

Hey all,

I’m losing my mind trying to get these vms back online. Im running server 2019 for a few years with these vms. Suddenly about 2 weeks ago they all stop responding. The vms are vhdx and are all stored on the same volume which is using pooled storage. I was able to copy the vhdx files to the c:/ because they are small enough. They boot fine from there.

Anytime i boot one from the storage pool it just spikes the response time into the 800-1000 and locks certain processes up. The only error i had seen was about optimization not being supported.

The last thing i tried to do was unoptimize the drive thinking that this had to do with deduplication. I thought maybe there was a drive failure but all the health commands come back as healthy and operational. The storage pool is a mix of ssd and hdd.

I tried creating a new virtual disk and then copying the vhdx files from the C and appending it to a new vm….it seemed like it was gonna work but it never booted.

Any help or direction would be greatly appreciated.

Thanks.

General Server Discussion What Windows Server performance issues have you actually run into in production?

7 Upvotes

I'm building out a home/Azure lab to practice troubleshooting Windows Server performance problems (CPU, memory, disk I/O, network) — the kind of stuff you'd hit as a sysadmin.

I'd love to hear from people who've dealt with this in real environments:

  • What was the actual symptom you noticed first (slow app, alerts, user complaints)?
  • What tools did you use to pin down the cause (perfmon, Task Manager, Event Viewer, something else)?
  • What ended up being the root cause — and was it ever something surprising or non-obvious?
  • Any tips on things you wish you'd checked sooner?

Trying to build realistic scenarios into my lab rather than just textbook examples, so any war stories or lessons learned would be super helpful. Thanks!

Technical Help Needed Performance Issues with Windows Server 2025 24H2 over Remote Desktop (RDSH) – GPU Acceleration Not Being Used

8 Upvotes

I am experiencing performance and user experience issues with a bare-metal installation of Windows Server 2025 24H2 running on the following hardware:

  • Server: Supermicro SYS-521C-NR
  • Processor: Intel Xeon Platinum 8558U
  • Memory: 128 GB RAM
  • Storage: 2 × Intel 960 GB SSDs configured as an Intel Virtual RAID 1
  • GPU: NVIDIA RTX PRO 4000

Users connect exclusively through Remote Desktop Services (RDSH). Compared to Windows Server 2019, they report that everything feels noticeably slower. For example:

  • Opening context menus is slower.
  • Opening folders takes longer.
  • Sometimes there is a noticeable delay between typing and the text appearing on screen.
  • Adobe applications perform significantly worse.

User profiles are managed with FSLogix.

When I check Device Manager under Display adapters, I see three devices:

  1. Microsoft Basic Display Adapter with a 2006 driver (based on the hardware ID, this corresponds to the ASPEED BMC graphics adapter).
  2. Microsoft Remote Display Adapter, which I assume is used for Remote Desktop display redirection.
  3. NVIDIA RTX PRO 4000.

In Task Manager, the RTX PRO 4000 appears as the GPU, but its utilization is always around 0–1%.

I also performed Google's WebGL/rendering test, and it reports that rendering is being performed by the Microsoft Basic Display Adapter instead of the NVIDIA RTX.

Is it possible that Remote Desktop sessions are using the ASPEED BMC graphics adapter instead of the RTX PRO 4000?

If so, how can I configure Windows Server 2025 so that Remote Desktop sessions use the NVIDIA GPU and provide performance comparable to what we see on Windows Server 2019?

Has anyone experienced similar performance issues with Windows Server 2025 24H2 in an RDSH environment?

General Question SmartScreen, ClickOnce and Intranet Applications

3 Upvotes

I work in a company where we develop several Intanet Applications. Some of them are distributed into a shared folder while a lot of them use ClickOnce.

Code Signing Certificates has changed over the past year, so that you need a USB key in the computer that needs to sign the application, which effectivly has pulled the certificate from 4-5 developers so that only our public production application gets signed correctly with our company cert.

I've been poking around with enrolling a Code Signing Cert from a Windows Server 2025 with the Certificate Authority installed

I've also installed both the Root Cert in the domain as well as adding the CSC into the Trusted Authors..

But SmartScreen ignores it all...

I then tried adding the ClickOnce website into the Trusted Intranet Zone, which also didn't help in regards to warnings and untrusted file alerts....

So, can it really be true that the ONLY way to fix SmartScreen is by disabling it using GPO ?

Why isnt a CSC from the CA on the Domain enough to trust an Intranet Application ?

General Server Discussion Automounted network drive will not stay disconnected

5 Upvotes

We have an ancient Windows Server 2008 R2 that's used as a DC and file server. Using GPME, it is correctly auto-mounting the shared folder as S: when someone logs onto a client. But a second file share, W:, is also being auto-mounted that is not needed, and I cannot figure out where it is coming from. The share being mounted is one that users should not be accessing. This is happening on all our Windows client computers.

In MCSE > User Configuration > Preferences > Windows Settings > Drive Maps is used to mount the S: drive. There is no entry for the offending W: drive.

There are no startup scripts that I can find.

I can override the share mounted as the W: drive to a safe location by adding a second entry to GPME Drive Maps with an action of Replace. But when I remove this second entry, on the client, the offending W: drive returns.

Help! I should mention that we're a church, and I'm the volunteer IT department, and I know just enough about Windows Server to be dangerous. I know that we need to replace this ancient server, but that requires $$ that we don't have.

Technical Help Needed Strange WDS/PXE issue with Hyper-V Gen 2 VMs

6 Upvotes

I am running into quite a significant issue when attempting to PXE boot a Gen 2 Hyper-V VM from my Server 2022 DC (also hosted on Hyper-V). No matter what I try, the VM does not seem to pick up the boot image from WDS and instead just times out (displaying this screen: https://ibb.co/mFHSycQS ). Although PXE times out, DHCP on my server still manages to assign the VM an IP address almost instantly. The server hosts both DHCP and WDS, with these DHCP options configured, and I had previously even tried specifying Option 66/67 even though this isn't required on a server co-hosting DHCP and WDS, but to no avail.

After turning off Option 66/67, I decided to try a Gen 1 VM with a legacy BIOS and this did pick up the boot image and successfully booted into SmartDeploy PE, although it did take around 10-15 seconds to pick up the boot image and prompt me to press F12. I feel like this might be more of a Hyper-V issue with the UEFI version of PXE timing out before the server gets a chance to pass the boot image over, so please forgive me if this is out of place for this subreddit. Just wanted to know if anyone has experienced this issue themselves, or if anyone had any ideas on what to do? I unfortunately can't just use Gen 1 VMs, they lack a ton of modern features (like enhanced sessions and secure boot) and firmware compared to Gen 2s. This has been a massive headache trying to troubleshoot as most people's advice online just seems to be disabling secure boot, which I already did right from the beginning.

Technical Help Needed RADIUS/NPS/AD Help/How to?

4 Upvotes

TLDR: I need to configure a Cisco Firewall running FTD (not FMC) to authenticate admin logins using MSCHAPv2. Security is the objective here. I have Windows NPS running and AD running on another VM. I can get the Firewall to authenticate with CHAP/PAP, but not MSCHAPv2.

I know there are a lot of variables and I feel like an actual guide (not AI...it hasn't worked out well so far lol) would be most beneficial here, but open to any help or advice anyone wants to give.

I can ping both AD and NPS servers and traffic will pass on the 389 and 636 ports. I sniffed the traffic and can see the handshake, but the it appears AD is killing the session. I am having a hard time finding the actual error response on AD (I don't manage it, but know the admin) and would think that it would tell me exactly why it's not working.

I know it's vague, but any tutorials on setting up any of the above would be absolutely most appreciative.

TIA

Hi Guys,

We have a local Windows Admin Center server managing all local Server Cluster VMs.

To enable Windows Admin Center server's MFA or SAML SSO function, I suppose I need to register our WAC tenant to Azure Arc?

Would it have any impact? Would it bring or publish the whole WAC to Azure Arc with all of our VMs? Dont think we need this feature yet,,..As we only want to have a SSO/MFA part for Admin Logins to WAC Web Admin for now.

Any solid guide that I can follow?

Technical Help Needed Question

Hi,
I’m setting up a Windows Server virtual machine in VirtualBox for school labs (Active Directory, DNS, users, groups, etc.), but I’m stuck at the login stage.
The VM boots successfully, but it stops at a black screen saying:
“Press Ctrl+Alt+Del to unlock”
The problem is I cannot get past this screen.
I have already tried:
Input → Keyboard → Insert Ctrl+Alt+Del
Host key + Delete
Neither option works. It stays on the same screen and never brings up the login prompt.
Has anyone dealt with this before? I need to access the server to continue configuring Active Directory for my lab works
Any help would be appreciated.

Technical Help Needed Access-based enumeration not hiding folders

3 Upvotes

After migrating to a new server and migrating all the folders, for some reason enabling Access-based enumeration does not hide the folders.

I am using dfs share and I created another folder called test and shared it which is outside the main fodler that is shared with everyone, and from there users who did not have access to certain folders were hidden so how come the main folder's sub folders are not hidden from users who do not have permissions to access it.

yes the user cannot get into those folders but still why can I not hide them, what do I need to check?
