I had the 3 Pc's conected in my own home LAN and when I use nbtstat -A 192.168.0.x all is ok, no matter with PC I use. Sorry if I didn't explain myself in my first post but the thing is that the nbtstat command doesn't work from my WinXP PC when I try to search IP addresses not over my own LAN but on the Internet. I have ADSL conection to Internet, obviously each PC is assigned with a different IP address each time I conect to the Internet, so to test I used nbtstat -A from WinME and Win98 using the IP addresses my PC's had in that moment and everything is OK, but not from WinXP. I had called some close friends when they are conected to the Internet to give me their IP addresses to test this problem, then I type nbtstat -A (IP address of my friend) but it still says "Host not found". I tried nbtstat -A from WinME and Win98 with the IP addresses of my friends and all's OK, it finds their NetBIOS names, but not with my WinXP PC. Again, what could it be?

Thanks for your help with problem #2, i'll try and see...
