I found a better solution (and the reason why we need a solution at all) regarding the recent DNS problems. As it turns out, AT&T *is* actually serving up DNS!! Problem is, they're changing which server is doing this *very* often - much more often than Windows 2000 or XP expects it. Seems that these latest flavors of Windows have a little service running known as "DNS caching". It's supposed to lock onto a DNS server (dynamically assigned, in AT&T's case) and use that server for the next 300 seconds (the default setting - hackable in the registry). The idea is, if your machine doesn't have to sense which DNS server is being assigned to it each time you click a link, your online experience should be marginally faster. Problem is, AT&T is probably switching between DNS servers faster than the expected 300 seconds and this explains why I can only get to about 7 sites at a time. If I leave it alone for a few minutes, I can grab another few pages - or I can force this process by refreshing my connection. All I had to do is go into "Services" and change DNS caching from Automatic to Manual and stop the service. DNS is once again set to dynamically grab whatever AT&T is throwing at me and pages are once again flying! My speed is still nailed at about 1.5mb/sec and I have the "piece of mind" of knowing that AT&T is at least providing the service they're being paid to provide. Win9x (Linux? Mac?) doesn't suffer from this new "feature" in 2000 or XP. While disabling it as I have is supposed to decrease web page flipping (since the system has to sense the DNS server each time), I honestly haven't noticed any difference. At least I have connectivity for all apps again! Just in case you're wondering, I found mention of this little goodie at: http://www.dslreports.com/forum/remark,1932223~root=attbi~mode=flat Please forward this tidbit to anyone you know might benefit from it.
