 Network Slowdown/Delay between XP and 2003 Server
Tech support, Networking, Security, Performance management, Servers, Microsoft Windows, Management, Bandwidth, OS, Desktops, SQL Server, Availability
I have several XP boxes sitting on an internal network behind a router. We use a Point-2-Point conection to get our office to our co-lo space where our server is located. This P2P is a T1. Our windows 2003 server is used as a document storage system that our xp boxes need access to continually. It seems that our server "loses connectivity" on a regular basis and when accessing the file system it slows down quite a bit. At times, it even times out. I am wondering if there isn't a setting/config that I have screwed up or forgot to take care of.

We have been suffering with this problem since day 1. Any help would be greatly appreciated. Thanks in advance.

How are you connecting to the T1? We had reliability problems with our T1s and I discovered neither end was supplying the clock. Notice the clock source command below.
Router A.
interface Serial0/0
description t1 to south campus
ip address xxx.yyy.zzz.aaa 255.255.255.252
no ip redirects
no ip proxy-arp
service-module t1 clock source internal
service-module t1 timeslots 1-24
!
Router B.
!
interface Serial0/0
description t1 to downtown
ip address xxx.yyy.zzz.aab 255.255.255.252
no ip redirects
no ip proxy-arp
service-module t1 timeslots 1-24

There are also ways to debug the T1 and the interfaces. In any event, you need to discover where the “lost connectivity” is happening. Have you tried trace route or pinging various points along the connection while the problem is happening?

Put the server in your office and backup the data to the off site colo box or other off site backups (probably cheaper). 100 mbps (std ethernet) is much faster - remember a T1 is just 1.5 mbps.

If it’s a cisco router, you can turn on NetFlow and collect statistics of the data traversing the P2P connection.
