T1 Networking DNS


P

Parvardigar

We have a small network, 15 users, behind a firewall, using Windows
Server 2000, Terminal Server 2000. The users complain that the
internet is too slow. We recently upgraded from DSL to a T1
connection. They thought we’d be faster. I phoned in Covad. They
tested the line and it ran at T1 speed. They suggested running a test
on our side. I ran a speed test on all the workstation computers. The
connections tested at around 1.5mbps.

One of the workers showed me a web site, Barrons.com. It took five
minutes to load up. I did the basics on his machine. Remove temp
files, defrag, cookies –the usual routines to cleanup a system. That
didn’t work. I took an unused computer added new memory, added a new
hard drive. Installed Windows 2000 and updated. A clean machine with
only windows installed. I brought Joe over to look at his new machine.
We launched Barrons.com, and it took five minutes to load up.

Here’s what I found out, and I was hoping this forum could help me
collect insight into a remedy.

The internal network is 192.168.254.xxx Gateway 255.255.255.0 DNS
192.168.254.5
We use DHCP to automatically obtain the addresses.

As an experiment I took this computer off our network and changed
‘obtain DNS’ to ‘use the following DNS server Address’. I put in the
generic 4.2.2.2 address. The web sites loaded up with blistering
speed!

And I tried the Covad address –74.2.131.xxx. The web sites loaded up
with blistering speed. This was most perplexing. I then returned the
computer to our network configuration, and alas, the connection speed
degraded remarkable.

I tested the line again. Though it proves we have T1 speed the
Internet connections within our company would prove the contrary.

Is there a remedy?
Thanks

What is between a desktop computer and the Internet? A proxy server, a
firewall, routers, etc.
