For currently running instances, no specific network configuration is required unless you decide to change the public IPv4 address of your instance.

In this case, the existing static configuration will remain and your instance will keep using the previous public IPv4 address. To enable DHCP configuration for your instance do the following prior to setting a new public IPv4 address.

<Message type=important> There is a risk of loosing network connectivity while doing the following steps. It is advisable to enable the serial console prior to run those steps so you keep serial access to your instance. The method is described in the document [Azure Serial Console for Windows](https://learn.microsoft.com/en-us/troubleshoot/azure/virtual-machines/windows/serial-console-windows)</Message>

This will ensure that DHCP network configuration is properly configured and activated in your windows instance.
13+
If you change the public IPv4 address, the Instance will retain its existing static configuration and continue using the previous address. To enable DHCP for your instance, follow our [dedicated documentation](/instances/troubleshooting/enabling-dhcp-network-configuration-windows-server-2022/) before updating the public IPv4 address.

12+
The latest Windows Server 2022 and Windows Server 2022 Core images on Scaleway Instances now use DHCP for network configuration by default. This aligns with the standard mechanism used across all Scaleway Instance OS images.
13+
14+
For existing running Instances, no changes to network configuration are necessary unless you plan to update the public IPv4 address. In such cases, the Instance may retain its static network configuration, continuing to use the previous public IPv4 address. To switch to DHCP and ensure the new address is applied correctly, follow the steps below to enable DHCP before assigning the new IP.
15+
16+
<Message type="important">
17+
These steps involve modifying network settings, which carry a risk of losing network connectivity (e.g., SSH or RDP access). To avoid this, enable and configure serial console access on your Instance beforehand. This allows you to maintain access via the Scaleway console even if standard network connections fail.
18+
</Message>
19+
20+
<Requirements />
21+
22+
- A Scaleway account logged into the [console](https://console.scaleway.com)
23+
- [Owner](/iam/concepts/#owner) status or [IAM permissions](/iam/concepts/#permission) allowing you to perform actions in the intended Organization
24+
- An [Instance](/instances/how-to/create-an-instance/) running Windows Server 2O22
25+

27+
## Enabling serial console access
28+
29+
Scaleway provides a serial console (TTY) for Instances, which is essential for troubleshooting network issues.
30+
For Windows Server Instances, you must configure the OS to enable the Special Administration Console (SAC) for serial access.
31+
32+
### Enabling SAC in Windows (OS Configuration)
33+
34+
Connect to your Windows Instance via RDP or another method and run the following commands in an elevated Command Prompt (Administrator) or PowerShell:
35+
36+
1. Enable Emergency Management Services (EMS):
37+
```
38+
bcdedit /emssettings EMSPORT:1
39+
bcdedit /ems {current} on
40+
```
41+
42+
2. (Optional but recommended) Enable the boot menu in serial console:
43+
```
44+
bcdedit /set {bootmgr} displaybootmenu yes
45+
bcdedit /set {bootmgr} timeout 10
46+
bcdedit /set {bootmgr} bootems yes
47+
```
48+
49+
3. Reboot the Instance for changes to take effect:
50+
```
51+
shutdown /r /t 0
52+
```
53+
54+
For more details, refer to [Microsoft's Azure Serial Console for Windows](https://learn.microsoft.com/en-us/troubleshoot/azure/virtual-machines/windows/serial-console-windows) documentation on enabling serial console for Windows VMs.
55+
56+
### Accesing the serial console via Scaleway console
57+
58+
1. Log in to the [Scaleway console](https://console.scaleway.com/).
59+
2. Navigate to **Compute** > **CPU & GPU Instances**.
60+
3. Click on the Instance your want to configure.
61+
4. On the Instance **Overview** page, click **Console** to open the serial console in a pop-up window.
62+
5. Once connected, you should see the SAC> prompt. Use commands like `cmd` to start a command channel, then `ch -si 1` to switch to it.
63+
64+
For more on using the Scaleway serial console, see [How to use the serial console to connect to an Instance](/instances/how-to/use-serial-console/).
65+
66+
## Steps to enable DHCP configuration
67+
68+
Once serial console access is confirmed, proceed to configure DHCP using the Server Configuration tool (sconfig) on your Windows Instance. You can access sconfig via RDP, PowerShell, or the serial console.
69+
70+
1. Open an elevated Command Prompt (Administrator) or PowerShell and run:
71+
```
72+
sconfig
73+
```
74+
75+
2. In the sconfig menu, select option **8** (Network settings).
76+
77+
3. Select the network adapter index (usually **1** for the primary adapter).
78+
79+
4. Select option **1** (Set network adapter address).
80+
81+
5. Choose **D** for DHCP.
82+
83+
6. The system will apply the changes and release any existing DHCP lease.
84+
85+
7. Return to the main menu and select option **13** (Restart server) to reboot and activate the configuration.
86+
<Message type="note">
87+
The reboot can be delayed if immediate downtime is not feasible, but it is required for full activation.
