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 into Covad. They
tested the line up to our box 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 DNS

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 address. The web sites loaded up with blistering

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. I
suspect everything has to do with DNS.

Is there a remedy?

Hello Parvardigar,

Please do not multipost the same question with different subjects. If you
do not find the posting you should think about using newsreaders to control
the overview. I think the "T1 Networking DNS" and "DNA Failure" postings
form yesterday belongs to this, where you also get some answer/questions.
Please stick to them.

Best regards
