Window 2000- Cleaning up

Hi Mike, I finished up the first posting to get Norton'sremoval up to 99.9%. Found a few registry entries but after rebooting, no change.

I will go on the the tweaks on Monday.. out of time today. Thanks again for your valiant efforts and remembering to be sure that I cover my as*!!

OK Larry

I guess all this is worth it since if we discover the problem here we can then fix all the other computers easily.

But a few questions.

Have you tested with the HW Firewall in the Router OFF?

Have you tested this with all other workstations off, just the server and this one workstation. It is possible you have a bad NIC on the LAN spewing out bad data and slowing system.

Are you using Switches or Hubs?

If using both is there a HUB in the path?

If you have a HUB or 10MB device (perhaps Router) in path from server to workstation then the speed will be the speed of the slowest device.

NIC speed 10/100 100 or 1000?

What brand of NIC?

A common diag on a NIC with a light is, RED=Problem, Amber=10 MB and Green=100MB. These are also on most brands of HUBS/Switches and Routers. If you have anything but green on this line thru the path from server to workstation then it will slow to the speed of the slowest device.

Do any of the Switches/HUBS or Routers have collision Diag lights and do you have collisions?

Hi Mike, I an not at work to day but let me fill in some info.

The server has a PCI-based embedded Gigabit controller, the NC7760, that goes to a Linksys 16-port Gigabit switch. No hubs. The workstation has a Linksys Gigabit NIC card. The equip upgrades were done a couple of months ago in hopes of speeding up MRI. They did nothing. I have replaced the server-switch cable (cat 5e) to eliminate wiring issues. Upon reflection, the firewall is part of the Two-Wire DSL modem so it is not in that loop after all.

I will look for indicator lights on the equipment on Monday. Don't know what DIAG/ collisions are.

A couple of side observations from playing around on Friday. The server also has MRI installed on it. If we use the workstation user's ID when running MRI at the server, it runs like a rocket ship! If we disconnect the ethernet cable at the workstation before trying to open MRI at the workstation, MRI will not open citing some kind of open wiring error (no server contact). To me, this info seems to only eliminate the software as both server and workstation have the same MRI version and updates. To you, it may mean more?

Thanks, Lar

 

Hi Larry

Then it is only protecting the Network from the Internet. That is OK but that does not protect the WorkStations from each other. Malware does not come from the Internet only, it can come from floppies, CD/DVD USB SD cards etc. and that is assuming something don't slip thru the HW Firewall also.

Don't do it until we are thru trouble shooting this issue but you may consider reactivating the Windows Firewall.

Larry it is looking for it's centralized Database on the server. It can not find it it won't run. Of course it will run on the Server as it is on that HD! That is the reason you have a Server so all the Data is available to all and not stored locally on the WorkStation. Does not eliminate the MRI software altho I never really thought it was. This is a network issue or a program or servive conflict.

Hi MIke,

Sounds like were in sync. Last on the current shopping list are the tweaks and the NIC lights. Thanks again, enjoy your weekend.

Hi Mike, had a few minutes today and both the Gigabit switch and NIC cards have two LEDs for each port. On the switch, the green one is the Link/Act LED and the other one is amber when there is a Gigabit connection (off otherwise). On the NIC cards incl the server) the colors are reversed. All are appropriately illuminated. The gigabit indicators are all solid.

Apprently, no colllision or DIAG indicators. Is there another way to determine this, if you feel that it would still be wise to do so?

Should I try running a home run from server to the workstation? Last time, I only went from the switch?

I also disconnected all other workstations from the network and tried MRI on our subject workstation but there was no improvement there, too.

Hi Larry

Been buried myself but had a few moments to log on.

Clarify that you have done the service tweaks on both the station and the server?

Also have you done the Speedguide link network tweaks?

Now for new approach.

On the Server how is the share set up? Is it a folder shared or an entire partition shared?

Do all work stations access the share as a drive letter? And if so what letter?

Answer these questions and I will post a new approach.

Mike
