[$50] Disabled networking on windows 2012 server

dodheimsgard

Hey guys,

I just disabled networking on windows 2012 server by accident (yes i know, im idiot). I can access server only with sysrcd. Is there any way to enable networking with sysrcd? Im willing to pay for help.

If it's a dedicated server, ask your provider if you can get access to KVM for the specific machine for a limited time. Usually most providers are able to give you access to the machine using a Lantronix spider or similar.

Well, not sure if this will work, but you can try creating a script with netsh, put that in the startup folder. That should be the easiest way to accomplish this.

Edit: I don't think this will work, I believe startup folder is executed at sign on, and since you have no way to sign on, they won't be executed.

@Prime404 thanks for this, but provider wont give me kvm so thats not an option.

Another method, may take a long time, dd the entire drive with sysrcd, gzip it, then restore to a local computer or something, fix networking and dd back. It's probably the slowest way to get this fixed but might be worth it of you don't want to reinstall and reconfigure everything.

can you start a registry editor from sysrcd?

Basically, this is what you need to do;
Please change two registries to resolve your issue:

1.Turn on Automatic Logon :
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
DefaultUserName :
DefaultPassword : < Local Admin Pwd>
AutoAdminLogon : 1

2.To run the netsh command to run automatically on a reboot.
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
Create a string value as enablenic with the value

Why not check if you do have IPMI with your server?

Hi.
Try to boot your system via qemu and access it via vnc. See troubleshoot in the following tutorial: http://www.danpros.com/2017/09/install-windows-on-any-server-using-rescue-system-and-qemu-kvm

You will not be able to directly enable the physical Ethernet adapter as the system is running in qemu and it shows you just the virtual network device. But you should find a way how enable it when you have full access to the system via vnc...

What provider are you using? Some may offer another type of KVM or iLO.

Well, wiping the Windows Installation isn't always needed in this case.

There's something called PowerShell and I've used it many times to fix my screwups on Windows...

Care to explain how you would solve OP's problem via powershell?
