Host name resolution failing on some Internet connections

[Dianne]

My laptop runs XP SP1, and I have wireless DSL at home.
On my DSL and on my company's LAN, my laptop has no
problem with host name resolution, but when I try to dial-
up or use other wireless networks, I can connect and ping
ip's, but host name resolution fails. Ipconfig /all
yields no DNS addresses. I have both the dial up and
wireless connections configured to obtain DNS
automatically and DHCP is enabled.

Ideas? Many, many thanks.

Dianne,

I haven't seen this particular problem before. Has it always
been like that or did it work and stopped working?

Just a few vague ideas. Have a look at your hosts file (in the
%windir%\system32\drivers\etc folder) and check for peculiar
content. Do a virus scan and also scan for adware and spyware
(use SpyBot, for example, a free download). Repair the IP stack
and Winsock, according to the procedures given in

Do you have any third party wireless or modem configuration
software installed? If so, uninstall it.

If all else fails, you could try a repair installation.
