Maybe a DNS problem. Are you getting DNS via DHCP assignment?

try:

host lxer.com

If that doesn't produce output like this;

# host lxer.com
lxer.com has address 207.210.216.38

then try it with a known to work DNS like this;

# host lxer.com 206.124.128.3
Using domain server:
Name: 206.124.128.3
Address: 206.124.128.3#53
Aliases:

lxer.com has address 207.210.216.38

You can try the same test with windows except use "nslookup" instead of "host". If
that is the problem (names aren't being resolved) and you're using DHCP then
correcting the DNS settings in your DHCP server may be necessary.
