I am withing my office network. Till date everything was ok but recently I started experienceing the issue of my IP address not being pinged from anywhere on the network even from machines withing the same subnet.
I am able to access the web, telnet into routers and pix firewall etc. But no one can ping my IP.
I had a static IP for myself but then ?I changed it and received a dynamic IP. Still the issue persists.
Looks like a strange problem. Try clearing the ARP cahce in you machine. Verify your DHCP configuration and check all the parameters you get from DHCP like IP address, subnet mask, default gateway etc and see if it is same as other machines in your network, except the IP address. Also make sure someone else is not using your IP addess.
First see if the ping request is reaching your host. If it is not, then the problem may not be in your host. If the ping request (ICMP Echo) reaches your host, but does not leave your host, then there is a problem in your machine. If it leaves your machine as (ICMP Echo-Reply), then again there could be network routing issue.
But I am wondering why people in your subnet is unable to ping you!?
