hi, iam using a LAN at my home . I have a laptop(vista) and a desktop(xp) both are connected to a wireless router from DLink 615 N-series router. Iam able to ping from my laptop to my desktop and able to share the files from desktop. But vice-versa, nothing is working. I mean from my desktop, iam unable to ping to my laptop and it displays "request time out".
why from one-direction it is only working and bi-directional it is not. I checked the windows firewall settings on desktop which is turned off. What is the reason? Iam using team-viewer on desktop only. Is that the reason or i need to turn some services on?
please help me.
thank u

The common cause of XP and Vista computers not getting along on a network is due to XP not having LLTD responder installed. You can find that here http://www.microsoft.com/downloads/details.aspx?familyid=4F01A31D-EE46-481E-BA11-37F485FA34EA&displaylang=en

You also need your XP computer to be on at least SP2 as well.
