Can you please show the output on the switch ports where those pc's are connected by using this command: sh int fastethernet 0/&lt;port number&gt; ?

To determine if the problem is with the computer or the network wiring or eqipment.<br />
<br />
Connect a laptop at temporarily at the locations of the desktop and test.<br />
Take note of the timing. If the timing is still an issue it could be a problem due to the wiring or<br />
the port where the wire is terminated in to the switch or router.<br />

Hi Guys,<br />
<br />
I found out that disabling the Windows firewall and Symantec Endpoint Security did not resolve the issue. Actually when removing Symantec Endpoint Security on both sides this brought down the latency to &lt;1ms. So in fact it was the disabled Symantec Endpoint Security which caused the problem. <br />
<br />
Thankx everyone!

Hi all,<br />
<br />
I have a problem on a local network with several PC&quot;s.<br />
<br />
When pinging any other device (cabled) on the LAN, the pingtime is 15 to 30ms. Other PC's on the same network are 1ms or less (&lt;1ms) which is usual. We updatet NIC drivers / changed NIC hardware, pinged other devices. Changed cables. We also pinged client to client with 2 static addresses. Results are no good. <br />
<br />
Anyone any ideas?

High ping time on local network test 15ms

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.

TCP/IP

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
