Connection issue

Question

Hi,

Anything is missing below? I want to put the proper IP address for it. Where is it?

Answer 1

Welcome to Microsoft Q&A,

Thank you for providing the additional details.

Based on your results, the server can reach external resources and successfully resolve DNS names, which indicates that basic network connectivity and name resolution are functioning correctly. This suggests the issue is likely related to the Remote Desktop configuration or connectivity path rather than the server's IP address settings.

To further troubleshoot the RDP connection on Windows Server 2022, please verify the following:

1.Ensure Remote Desktop is enabled under System Properties > Remote.

2.Confirm that the Remote Desktop Services (TermService) service is running.

3.Verify that the server is listening on the default RDP port (TCP 3389): netstat -ano | find "3389"

4.Confirm that Remote Desktop has not been disabled by policy or registry settings:

reg query "HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections

The value should be 0, which indicates that Remote Desktop connections are allowed.

5.Verify that Windows Defender Firewall or any network firewall allows inbound RDP traffic on TCP port 3389.

6.Test connectivity to the RDP port from the client machine: Test-NetConnection <ServerIP> -Port 3389

7.If the service is running and port 3389 is reachable, consider temporarily disabling Network Level Authentication (NLA) for testing purposes, as authentication or certificate-related issues can sometimes prevent RDP connections even when network connectivity is healthy.

The most common causes of this behavior are the RDP service not listening correctly, Windows Firewall blocking port 3389, Group Policy restrictions, or NLA/certificate-related issues. Focusing on these areas should help identify and resolve the connection problem.

Hi,

from the screenshot you shared, the system currently shows “You are not connected to any networks.” That means there is no active adapter bound to an IP address at the moment. To assign a proper IP, you need to go into Change adapter settings on the left pane, right‑click the relevant network adapter (Ethernet or Wi‑Fi), choose Properties, then highlight Internet Protocol Version 4 (TCP/IPv4) and click Properties.

In that dialog you can either set the IP manually (for example 192.168.x.x with the correct subnet mask and gateway) or leave it on “Obtain an IP address automatically” if DHCP is available in your environment. If you are unsure of the correct values, check with your network administrator or run ipconfig /all on another machine in the same subnet to see the addressing scheme.

Without configuring the adapter here, the system will remain disconnected and no IP will be assigned. Once you set the IP correctly, the Network and Sharing Center will show the active network and you’ll be able to connect.

I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!

To enter a static IP address in Windows:

1. Open Control Panel > Network and Sharing Center.
2. Select Change adapter settings.
3. Right-click the network adapter, then select Properties.
4. Open the Internet Protocol settings for the adapter.
5. Select Use the following IP address.
6. Enter:
   • IP address: a unique address available on the network
   • Subnet mask: the subnet mask for the network
   • Default gateway: the IP address of the device that connects the network to the Internet or another network
   • Preferred DNS server and Alternate DNS server: the DNS server IP addresses
7. Select OK, then close the remaining dialogs.

The correct IP address is not shown in that screen. It must come from the network configuration used by that network. If the wrong values are entered:

• A duplicate IP causes an IP address conflict.
• A wrong subnet mask can prevent access to other computers on the network.
• A wrong DNS server can prevent name resolution and internet browsing by host name.
