Your screenshot confirms:
IPv4 Address: 192.168.55.20 (Duplicate)
Autoconfiguration IPv4 Address: 169.254.245.211
So Windows is still rejecting 192.168.55.20. Use a different member-server IP, such as:
192.168.55.21
Run these on MEM01/member VM as Administrator.
1. Remove the bad duplicate IP
Get-NetIPAddress -InterfaceAlias "Ethernet" -AddressFamily IPv4 |
Where-Object { $_.IPAddress -like "192.168.55.*" } |
Remove-NetIPAddress -Confirm:$false
2. Restart the adapter
Restart-NetAdapter -Name "Ethernet"
3. Assign a new IP
New-NetIPAddress `
-InterfaceAlias "Ethernet" `
-IPAddress 192.168.55.21 `
-PrefixLength 24
Do not add a default gateway for host-only network.
4. Set DNS to the Domain Controller
Set-DnsClientServerAddress `
-InterfaceAlias "Ethernet" `
-ServerAddresses 192.168.55.10
5. Verify
ipconfig /all
You want:
IPv4 Address: 192.168.55.21
Subnet Mask: 255.255.255.0
DNS Servers: 192.168.55.10
No (Duplicate).
6. Test
ping 192.168.55.10
Resolve-DnsName powershell.local -Server 192.168.55.10
Your final setup becomes:
Windows 11 host: 192.168.55.1
DC01: 192.168.55.10
MEM01: 192.168.55.21
Also make sure no other VM is running with 192.168.55.20. The duplicate message usually means another machine already has that IP, or the clone/network adapter still has a conflict.
