How is it possible that I can ping the server, but the server cannot ping a workstation

I have about 70 computers on a internal domain.  The server is a windows 2000 server.  Most work stations are windows 2000, 10 XP and 2-3 vista.

I am trying to trouble shoot some network issues.  I have found 1 bad switch and have replaced it with a new one.  In many ways our connection issue has resolved itself.

But the big mystery that I need help with is this:

The work station can ping the server with 0% loss now.  It has to go through 4 or 5 switches to get to the server.  The server has 100% loss pinging the work station that I just pinged it from.  So it is going through the same set of switches.

The firewalls are off.

How can this be??  Is it possible that there is still a bad switch?  

I am stumped.  Any help would be greatly appreciated.

is it a managed or unmanged switch.
can you put the pc on the first switch and ping it or just put a laptop at the pc location and try pining it.

what are the switches.

Are you pinging by IP or computer name?
Could be a DNS issues if by name.
Try pinging both by IP and name and report back the results please.

Another chance is to look for antivirus or personal firewalls installed on the workstation.

All switches unmanaged.

I am using IP addresses.

I tried several internal computer names and they pinged fine.

One of the computers I was trying to ping is a wireless laptop and it likely has a firewall turned on.  I did find a firewall active on one of the other work stations I was trying to ping.

I am thinking the internal pinging may be fine.  I think I was in error in some way.

HOWEVER

The server has internet access, yet cannot ping reliably to an outside address.

Example:  I got a 71% loss (100 pings) pinging to outside address from the server.

I got 1% loss pinging from a work station next to the server to the same outside address.

network card on server seems fine.  Or at least it pings itself without loss.

Any ideas?

Thank you.

Try to change the network cable for the server.
Another try is to connect the server and one client to a test switch and see if they can ping each other

As Point-In-Cyberspace has sugested - change the LAN cable.  I had an issue where I was getting intermittent ping replies from my server and I was only pinging the router!
Changing the cable worked like a charm.  Weird - they just stop working properly despite not being touched / moved for ages!

i would try pinging to the localhost (loopback) to prove it out.

can you not put the laptop and the server connected up using a cross over cable this will take all the devices out of the equation and work backwards to see where the loss is happeing.

What happens if you do a pathping or a tracert.

Sorry for the long delay for a response.

I am still baffled.  The issue seems resolved.  I can now ping without loss to the outside world.  I did change the cable.  but it seemed to be fine before I made the change.  I changed it in case there was a loose connection.  thank you for all you input.
