1. CCP vs. SCP Architecture
New Netcup users often confuse the two distinct web interfaces provided by the hoster:
🏢 CCP (Customer Control Panel)
customercontrolpanel.de: Administrative and billing portal. Used for contract management, invoices, tax-exemption verification, and cancellation notices.
🖥️ SCP (Server Control Panel)
servercontrolpanel.de: Hardware-level KVM hypervisor portal. Used for power controls, mounting custom ISO images, HTML5 VNC console, and rDNS/PTR configuration.
2. Windows ISO & VirtIO Drivers
Because Windows does not bundle open-source RedHat KVM VirtIO drivers out of the box, booting a standard Windows ISO will fail at disk selection with "No drives were found".
💡 Netcup Pre-loads VirtIO Drivers:
You do not need to download virtio-win.iso manually. Netcup already provides the official VirtIO driver disk directly in the SCP DVD drive selector.
3. Step-by-Step SCP Mount & VNC
Mount Custom ISO in SCP
In SCP, navigate to Media ➔ DVD drive ➔ Upload/Own Images. Enter your Windows ISO direct URL. Once fetched, set DVD drive as first boot priority.
Launch HTML5 VNC Console
Click "Screen" to launch the HTML5 KVM console. Send Ctrl+Alt+Del via the Power menu and hit Enter quickly when "Press any key to boot from CD" appears.
Load VirtIO Drivers
At the Windows disk selection screen, click "Load Driver" ➔ browse to the VirtIO driver disk ➔ select vioscsi (storage) and NetKVM (network). Your NVMe drive will appear instantly.
4. Fix: Gateway Outside Subnet
Upon initial Windows reboot, network connectivity will show no internet. Netcup uses point-to-point network routing where your assigned gateway (e.g., 45.158.40.1) does not reside inside your server subnet (e.g., 202.61.200.50/32). Windows refuses off-subnet default gateways unless explicitly configured.
REM 1. Identify network adapter name (usually "Ethernet")
netsh interface ipv4 show interfaces
REM 2. Assign static server IP and /32 subnet mask
netsh interface ipv4 set address name="Ethernet" static YOUR_SERVER_IP 255.255.255.255 none
REM 3. Critical: Add On-link direct route to off-subnet gateway
route add YOUR_GATEWAY_IP mask 255.255.255.255 0.0.0.0 if 1 -p
REM 4. Set default route pointing to this gateway
route add 0.0.0.0 mask 0.0.0.0 YOUR_GATEWAY_IP -p
REM 5. Configure public DNS resolvers
netsh interface ipv4 set dns name="Ethernet" static 1.1.1.1 primary
netsh interface ipv4 add dns name="Ethernet" 8.8.8.8 index=2
Once executed, run "ping 1.1.1.1". Network access will initialize immediately.
5. Enabling Native 3389 RDP
Enable Remote Desktop in Windows Settings ➔ System ➔ Remote Desktop. Connect directly from your local machine using Microsoft Remote Desktop (mstsc) on port 3389.
