SBS Network - 30 users - T1 Slow

[adamroof]

Hey all, just wanted to run this by you.

We have had our T1 for about 4 months now, and overall it seems slower than our previous business SDSL 1.5M connection. I thought the T1 was supposed to allow for stronger connections, not really faster, but stronger. It was supposed to allow for stronger video streaming without interfering with other users internet traffic.

Maybe i am not utilizing these features properly or its SBS itself??? Is it the firewall limitation?? Are our switches failing us?

Our internal traffic seems to run fine, we have about 25 to 30 WinXP boxes chatting away with our exchange and sql and net shares all day, and that doesnt seem to slow down, but when one user opens up streaming video, i get "Why did we go back to dial-up" questions. It really isnt that bad, but i have been doing some traffic graphing from the SBS server and im seeing the users watch the Masters Live, and then our Verizon DNS server latency sensor chart goes from 11ms to a steady 500ms.

30 Workstations, 1 SBS (DC/Intranet) , 1 Win 2003 (net sharing/App/BBerry), 1 Cisco Pix 501 Unlimited User, 1 Verizon T1

the first place you should start is by calling verizon to get visibility into your link utilization.

Adam,
Ive pulled the PMONS usage on your T1 circuit and can see nothing there that would cause a problem.

PS - 3 26 port HP ProCurve switches too / latest firmware / Commander stacked

use wireshark or etherreal to monitor a slow workstation. it can tell you what may be your bottle neck. perform a few tracert's out to web addresses and see if there is a latency section. verify your PC's are using the right Gateway address. Also, verify there is not local LAN loop happening. Also, have someone verify your PIX and Routers is configured properly and not NIC speed linmited.
