There's a known issue when attempting to configure a network adapter to set a static IP address through SConfig on a freshly installed Windows Server 2022 Core. Upon attempting to configure the IP address, it will fail with the following error message:

Error

Setting NIC to static IP...

Failed to release DHCP lease.

Result code: 83
Method name: ReleaseDHCPLease

You can manually work around the issue by configuring the IP address using Powershell directly:

1. First, list all network adapters present to find the correct one:

   Get-NetAdapter

   You can reference by Name (InterfaceAlias) or by ifIndex (InterfaceIndex).
2. Next, remove any existing (APIPA) addresses:

   Remove-NetIPAddress -InterfaceAlias Ethernet0 -Confirm:$False

3. Add the new IP address to configure:

   New-NetIPAddress -InterfaceAlias Ethernet0 -IPAddress 10.20.30.10 -PrefixLength 24 -DefaultGateway 10.20.30.1

4. Optionally, set the DNS servers. Note that this bit is not bugged and can be performed via SConfig:

   Set-DnsClientServerAddress -InterfaceAlias Ethernet0 -ServerAddresses ("10.20.30.2","10.20.30.3")
