PC Slow on one network segment
Ok. I have 2 PC's that at one location called site A are running very slow but when I bring them to site b they speed up considerably. Site A and B are connected via Gig Fiber. I also changed the connection type to wireless but it made no diffrence. I replaced the switch at site a. Still no change. Disabled every other device on the switch at site A except one PC and the fiber connection to site B. No change. I am running out of things to replace. No spyware or virues on PC's either. Any suggestions would be welcomed.

You're segmenting with a switch? Is it a layer 3 switch or a router?
Are they are on the same network?
Same Subnetmask?
What are the ips of router/switch a and b
Copy and paste ipconfig/all from one machine on the A network and one on the B network.
Thank!

They are on the Same network, IP of Client is 10.31.8.5 Mask 255.255.255.0 Gate 10.31.8.1. Server is 10.31.4.5 Mask 255.255.255.0 THe only router is our core router at the servers location. Took the client PC to another location and it works fine from there. Tried 2 different routes, one fiber one wireless but both have same result. Replaced switch at client location still no change. Bypassed swith altogether at client location, no change.

When you login to the switch and do a tracert, and ping, what are the results?

Pings & tracert are good and with quick responses from both the switch and PC.

Running applications from the server. One in particular opens in 10 sec at every other location but at that site it takes 3 min. Browsing and opening files on multiple servers is not as fast as at other locations.

I will have to get out to that location so it will take some time. But every tracert I ran went like this. 2 hops. First 10.31.1.1 ( our core router) Second was the server. Responses were 5-8 ms.

Passes through the switch. Switched network not routed network.

I have a few questions for you as well. You said that the locations are connected via fiber. How far apart are they? Is the fiber multi-mode or single mode? If it is multi-mode, then it will support GB connections however 50/125 fiber is preferred over 62.5/125 for longer distances (2000 meters vs. 700 meters). Is it owned buy you or is it leased?
Where are your routers (10.31.8.1 and 10.31.4.5) located at? You stated that they are on the same network but they are not. Both networks are Class C's so they have different network ID's.
The Client is 10.31.4.0 and the server is 10.31.8.0.
As to the switches, the previous posts have some good questions for you. What type are they? Are they managed switches? Are you using VLAN's?

Exactly!
Either you are routing via a router or through VLAN's in your switch. You have configured your server and your client on two separate network ID's. Your "Core" router would have to be aware of both networks with a route table and it would have an IP address visible on both networks.

Yes, typo on my part. I am so used to seeing the 10. Networks as a Class A.

Can you capture and post a Tracert from your client PC to your server?
Have you checked the Event Logs on your switches for errors? Can you check the Port statistics to see if there are any drops or errors? Is Spanning Tree Protocol enabled in your switches and do you see any STP errors?

I asked him to do that a while back but he said he'd have to go onsite so I am guessing he's doing so... or maybe on another service call?

Let me try to explain by using your picture. Site A PC1(10.31.8.69) Switch 10.31.8.11
From there fiber to Core Switch/Router Which has Route tables
And IP 10.31.8.1, 10.31.7.1 etc.
Site B has switch 10.31.1.11 and server 10.31.4.38
