Ping Driving me Crazy....

[Jason Staudenmayer]

Just bcos you have a Cisco switch doesn't mean it can't break. The good
switches but they're not indestructible. Also look at the cables themselves
are the bough or made? I had a very 
similar problem a few years ago and it turned out to be the switch I was
using. Never rule out anything based on a product name, they all break,
eventually.

Hi All,

Well let me add something more, this has started happening since a couple of
days,do any of you think it could be bcos Eth1 which is the Internal
Interface is  getting clogged with the number of requests that are coming
from the Windows Clients?and morever bcos of the Blaster Virus and
Vulnerablities on Ports 135:139, the network may be getting jammed and hance
not accepting the ping requests!Therefore is it wise to increase the Buffer
Limits of TCP requests ?If yes can I know how it can be done?

I have also attached the Firewall script that I am using.

And Yah cant be a Rj 45/switch issue bcos I am using a Cisco Catalyst 2900
switch, which is fairly a great switch to have.

Your thoughts on this will be helpful.

Harry
