Cannot Ping on Networked computer

[mukeshhtrivedi]

Hi,
My Windows XP SP2 computer is connected to my office network and it
works fine on network I can access all network resources even other
network computer can login to my computer using Remote Desktop
Connection and Backup Exec Server can select my file/folder but if any
computer try to ping my computer they can't. Last week we checked and
was able to ping but suddenly what could have happen. Can anybody tell
me please.

Thanks,
Mukesh

I would be inclined to check to see if your firewall (assuming it's on)
discards PINGs.

Thanks Wiley. I checked firewall and it seems to be ok.

Can you PING another system?

Thanks Wiley. I checked firewall and it seems to be ok.

Can you PING another system?

Okay, so I asked because I had this issue about 6 months ago, ping out, but
not in.

SO, I grabbed the latest driver from the vendor web site and installed.
Voila - all was good. It seems that something went goofy with the
transceiver on the NIC (according to 3COM, it has something to do with a
"Negative Pulse???" on the transceiver). Don't know, just that it worked.

If that fails, try a different NIC. I will gaurentee that it is the NIC, not
you or the OS etc.

Hope it helps, let us know.

Wiley.

Well Thanks for all your help.

However its amazing. I turn off the Firewall and turn on and again turn
off and restarted computer and it works now. i don't know how it
happened but this is fact.

Now I can ping without any problem.

It is completely plausible that the firewall had knocked the
local domain off its trusted site list. The firewall would then
block the response to the incoming ping from any remote system,
including those locally. Resetting the firewall and computer
must have restored the trusted zone.
