DHCP address received but NO connection established?!

Please help,

I have one computer connected to my network which receives a dynamic IP from
the DHCP server, but so strangely, after it does so, no connection is
established with any machine in the network even the DHCP server itself!!!
I tried releasing and renewing the IP address, tried giving it a static IP,
returned back to dynamic address but no luck at all?? The machine only pings
itself in the loopback.
Can anyone give me a suggestion please?

Thank you all,

Tom Marcony

It sounds like you have a firewall blocking lan traffic. What kind of
firewall do you have in place?

Check from the hardware level up.
1. Check cable
2. Check NIC driver
3. Check IP Configuration DNS, Subnet Mask, WINS, etc..
 
This may sound stupid but a friend of mine had this situation with his PC.
As an old-timer from the days of ISA slots in computers I knew that some
unexplained problems are IRQ related and not very obvious. Some of these IRQ
problems are still present in the new PCI computers specially when certain
cards try to monopolize some interrupts.
What I had my friend to do was shut down the system, remove his network card
(if the network card is build in, then remove any other card that may be in
the system besides the video card). Boot with out the removed card. Shut
down again and replace the card.
That solved my friends problem. What has happened is that somehow the system
assigned the same IRQ to cards that it was not supposed to with out
triggering any "red flags". By removing this card, the system was given
opportunity to re-assign and this time it did it correctly.
