I have a simple network between Windows XP and Windows 7 with crossover cable.


Windows 7 computer is acting as a router with two LAN cards (onboard and PCI).

Onboard card settings:

  • Obtain an IP address automatically
  • Preferred dns server : 81.91.129.67
  • Alternate dns server : 4.2.2.4
  • Shared

So everything should be okay on Windows 7 computer.

PCI card on Windows 7 computer:

  • IP address: 192.168.2.11
  • Netmask: 255.255.255.0
  • 0.0.0.0
  • Computer name : cougar
  • workgroup : nethome

Everything is off in network options except File & Printer sharing.


PC with Windows XP:

  • IP address: 192.168.2.12
  • Netmask: 255.255.255.0
  • Gateway: 192.168.2.11
  • DNS: 4.2.2.4, 8.8.8.8
  • computer name : tiger
  • workgroup : nethome

Both have connection to internet, and both can see each other by using IP (\\192.168.2.11 and \\192.168.2.12).

Problem is when in XP I try to go to \\cougar, it says there is an error with network path.

In Windows 7 PC \\tiger works perfectly.

What might be the problem with Windows XP PC?

Few days ago this network was working okay, when both computers ran Windows XP.

Another problem is that I can't find tiger in "Homegroup" in Windows 7 PC. Is there any way to fix this?
