Windows 7 Network problems between Windows 7 and XP

[MBaeten]

Hi,
I have 2 pc's in a netwerk and a SMC router (4 ports and Wireless)
Both computers are connected to the Router with cable and wireless.
From Both computers I can acces the internet (Router is also gateway)
So I have 4 IP-adresses:
- XP 192.168.200.100 (wireless)
- XP 192.168.200.103 (LAN)
- W7 192.168.200.101 (Wireless)
- W7 192.168.200.102 (LAN)

When I do a ping from the XP pc to the windows 7 PC (..101 or 102) I get a reply from the network adapter of the WIndows 7.
But when I do the same on the Windows 7 PC to the XP pc (..100 or 103) I don't get a reply.
Why ??

It sounds like you are experiencing connectivity issues between your Windows 7 PC and your XP PC on your network. When you are able to ping from one PC to another on a local network but not vice versa, there are a few common reasons why this might be happening:

1. Firewall Settings: Check the firewall settings on both the Windows 7 and XP PCs. Firewalls can block ping requests. Ensure that the firewall settings allow ICMP (Internet Control Message Protocol) traffic for ping requests.
2. Network Discovery and File Sharing Settings: Ensure that both PCs have network discovery and file sharing enabled. This allows the PCs to be visible on the network and respond to requests.
3. Network Profile: On both Windows 7 and XP, check if the network profile is set to "Private" or "Home" network. Public network settings can sometimes restrict communication.
4. Network Configuration: Check the network configuration to ensure that both PCs are on the same subnet mask and have the correct IP addresses. Verify that the default gateway is set correctly on both PCs.
5. Antivirus Software: Some antivirus software can block network communication. Temporarily disable antivirus software to see if it is causing the issue.
6. Network Adapter Settings: Check the network adapter settings on both PCs to ensure they don't have any conflicting configurations. To troubleshoot and resolve the issue, you can try the following steps:
   • Disable the firewall temporarily on both PCs and attempt to ping again.
   • Check and ensure that network discovery and file sharing are enabled on both PCs.
   • Verify the network configuration settings (subnet mask, default gateway, IP addresses).
   • Temporarily disable antivirus software and attempt the ping.
   • Check for any errors in the Event Viewer on both PCs that might give a clue about the issue.
   By checking these settings and making the necessary adjustments, you should be able to establish successful communication between your Windows 7 and XP PCs on the network.
