Have you tried doing all the Windows updates and Office updates on these systems?

Check event logs on the systems and servers for anything wierd.

Any strange processes running/using up system resources?

Is it just the applications that are running slow or does it appear to be network connectivity that is slow or both?

Hi there,

the problem is the conection speed of your NIC,

If you have a Switch of the Speed 10/100 with autonegotiation

your switch turns to 100 Mbit half duplex. That means you have many colisions on

your ethernet connection. If you have a managed switch turn both the port speed of the switch and the portspeed of the NIC manually to 100 Mbit full duplex .

The reason is that the NIC tries to handle out the Speed from 1000 mbit which the switch couldn´t handle.

The next step is to update your NICdriver to Version 7.4 ( Download from INTEL)

I hope i could help

Thank, Helper 007!

I believe you may provide the solution to solve the problem.  Can you tell me how I can correct the NIC settings?  Do I need to change the setting in this GX 270 computer or the WIN 2000 Server?  Can you also tell me from where I can download the driver?  I searched Intel' website for almost an hour and did not find the driver download link.  Sorry I am not a computer person and I am eager to learn.

Thanks again!

I'm not really sure how Helper diagnosed this based on the info you originally provided.  I find it hard to believe the switch is the culprit here as there are two other machines autonegotiating fine.  Plus the 170 (also with the same XP load apparently) I don't think has a gigabit ethernet.  I mean I'd be more inclined to think of something like DNS or some kind of routing problem.  Can you tell us what kind of switch you have and wether you are running your own DNS server?  It might be possible the XP NIC drivers are choking on something but let's start simple...

Try deleting the network adapters in the device manager (Start-->rightclick My Computer-->Properties-->Hardware-->Device Manager then expand the network adapter group, highlight the card and press delete).  Then restart the machine and let Windows reinstall the device on its own.

If that doesn't work, lets quickly update Office to the latest service pack (http://office.microsoft.com/OfficeUpdate)  Keep running the update until MS tells you you have all updates.  While you're at it, maybe we should run all the Windows updates (windowsupdate.microsoft.com) and make sure you install all the critical updates and service packs as well as any driver updates they recommend.  This shouldn't take too long and its a good thing to do (yes I am well aware MS updates sometimes do wreck stuff but they help more often than not). 

This should take no more than an hour total and give us a good starting point.

Ok,

here you can get your NIC Driver

select your OS and than Download.

P.S.:

I had this problem in a Network with over 400 Clients.

Round about 200 where GX 270 with GigEth NIC´s

The bad connection between those and some Server´s made the whole Network Slow.

My Dell computer is slow also. It's CPU is Pentium 4 2.4GHz. When I try to import video into Windows Video Maker from my Sony handycam the video it gets all choppy. I have had to shut down too many programs too many times by force(Ctrl+Alt+Del). Have you tried a different Anti Virus program? AVG is free and it works very well. You may need to get the full version if you are with a business. Here is the address to get it. http://free.grisoft.com/freeweb.php/doc/2/. Well good luck with it with any of the three solutions that were given to you.
