I can ping a XP machine from my 7 machine. XP machine cannot ping back

[mmeowcusa]

both are connected to the same router
the ip of the 7 machine is 192.168.1.102 and the default gateway is 192.168.1.1
the ip of the XP machine is 10.1.10.22 and the default gateway is 10.1.10.1

the 7 machine can ping both 10.1.10.22 and 10.1.10.1 and receive responses. I can even access the sharing on the xp machine by typing \\10.1.10.22 into my windows explorer, but the xp machine cannot ping or access \\192.168.1.102

this is really weird. I mean, for starters, it would appear that this router somehow has two ip addresses, secondly, I can ping AND get a response from one machine, but nothing from another.

I have no idea what's wrong

Hi mmeowcusa and welcome to Seven Forums.

Could you on both machines open command prompt by going to start - type in the search bar "cmd" - right click and run as administrator. (For windows 7 only)

For windows XP to open cmd- start - all programs - accessories - command prompt - right click run as administrator

type the following commands.

 ipconfig /release

 ipconfig /renew

Post back your results.

I would guess that you have an alternate IP address added on the 7 machine.

On the 7 machine, please go to: Network and sharing center --> Change adapter settings --> Double click network connection icon --> Double click TCP/IPv4 --> Advanced...

In the IP address box...is there another IP address like 10.1.10...somewhat?
