Windows XP Netbios Problem

[dougie1809]

Hi,

I am running windows 7 on my host machine, and also running virtualbox with windows xp.
I have internet running on the host and the VM using the same LAN network (home network).
But I have a netbios problem on XP even though I have netbios enabled in network connection properties. Even worse I cannot ping the VM XP with my host windows 7, but I can ping windows 7 with the VM XP ?
I can also ping VM XP with its loopback address and its own IP address?

Any suggestions?

Thanks for future help

It seems like you are experiencing some networking issues with your Windows XP virtual machine running on VirtualBox alongside your Windows 7 host machine. The fact that you can ping the Windows XP VM from itself but not from the host machine raises some networking configuration questions. Here are some suggestions to troubleshoot and potentially resolve this issue:

Check Network Configuration:​

1. Network Adapter Settings: Ensure that the network adapter in the VirtualBox settings for the Windows XP VM is set to the appropriate mode. Usually, "Bridged Adapter" or "NAT" works well for communicating between the host and guest.
2. Firewall Settings: Check the firewall settings on both machines (Windows XP VM and Windows 7 host) to make sure they are not blocking ICMP requests and other network traffic.

   Troubleshooting Steps:​

3. Restart Networking Services: Sometimes restarting the networking services on both the host and guest machines can resolve connectivity issues. You can do this by disabling and re-enabling the network adapter in the network settings.
4. Network Sharing Settings: Make sure that network sharing is enabled on both Windows XP VM and Windows 7 host. This includes enabling File and Printer Sharing and ensuring that the machines are on the same workgroup.

   Verify Connectivity:​

5. Check IP Configuration: Confirm that both the Windows XP VM and Windows 7 host are on the same subnet. You can do this by checking the IP addresses and subnet masks configured on both machines.
6. Flush DNS: In some cases, flushing the DNS cache on both the host and guest machines can help resolve connectivity issues. You can do this by running the command ipconfig /flushdns in the command prompt.

   Additional Steps:​

7. Network Troubleshooter: Use the built-in network troubleshooter on both Windows 7 and Windows XP to diagnose and potentially fix any network-related issues automatically.
8. Update VirtualBox: Ensure that you are using the latest version of VirtualBox, as updates often include improvements and bug fixes related to networking.
