Wayne:

Here are some ideas.

You can tell if the problem is related to a DNS lookup thing or a
network thing by pinging an IP address rather than a host name. Once
the connect seems to be established, type: ping 206.53.103.2 and see
if you get a response. If so then double check the entries in
/etc/resolv.conf and /etc/host.conf.

If you get no response from the ping, then you have some other
problem. From root, type ifconfig. Make sure that you get an entry for
your ppp interface. It should look something like this:

ppp0      Link encap:Point-to-Point Protocol
          inet addr:206.53.100.237  P-t-P:206.53.100.251 Mask:255.255.255.0
          UP POINTOPOINT RUNNING  MTU:1500  Metric:1
          RX packets:128 errors:0 dropped:0 overruns:0 frame:0
          TX packets:166 errors:0 dropped:0 overruns:0 carrier:0 coll:0

Then type netstat -r. It should look something like this:

Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window irtt Iface
ts2.southwind.n *               255.255.255.255 UH     1500 0        0 ppp0
loopback        *               255.0.0.0       U      3584 0        0 lo
default         ts2.southwind.n 0.0.0.0         UG     1500 0        0 ppp0

Make sure that there is a default route. If not, make sure that
defaultroute is included in the /etc/ppp/options files.

Let us know what you find out.
