DHCP

[Chris]

My computer quit receiving its dhcp address and will not
recognize the network..So i put in a static ip just like
one of our servers, now it recognizes the network but it
still will not let me on the internet. The server with
the static ip will get on the internet.. I have tried
everything.. Please help

Is this computer joined to the network? What kind of a network? Can you give
us a ipconfig/all?

What precisely do you mean by "quit receiving" its DHCP
address? You mean the DHCP server stopped, and no longer
renews leases? Or you literally mean that the computer in
question can no longer recognize DHCP commands that it
receives?

Seems to me the solution lays in restoring DHCP first.

The reason that you can't reach the Internet is that your
system doesn't have a default gateway defined -- it learns
not only its IP address, but also the default gateway from
the DHCP server; you can manually configure a default
gateway if you wish, but (to be redundant) you really need
to figure out why DHCP stopped working.

Once this is done, your static route will handle all
packets to the specified subnet, and all other packets
will be forwarded to the default gateway IP address.

Yes it is on small star network with 2 file servers 1 router and 2
switches.. there are about 15 computers and 2 netowork printers.
The ipconfig/all says
host name computer-xxxxxx
primary dns suffix (blank)
node type broadcast
ip routing enabled no
wins proxy enabled no
physical address...
dhcp enabled yes
autonconfiguration enabled 169.254.90.xxx (which it shouldn't)
subnet mask 255.255.0.0
default gateway (blank)
dns servers (blank)

Did you check the networkcable? If you put in an IP yourself (with the right
subnetmask, and the gateway pointing to your server-IP), is it working then?

Hello Chris,

I have a few questions for you, if you don't mind.

1.) Do other computers on the same subnet have this problem?
2.) Has your scope run out of leases? Is it full and has exceeded its
capacity?
3.) Do you have logging enabled on the DHCP server?
4.) Can you verify that any dhcp relay agent has not changed any?

I would make sure that DHCP logging is enabled on the DHCP server and see
if you see any requests being recieved from the client.
I would them take a netmon trace from the client and the DHCP server in
order to see what exactly is taking place on the wire.

I did put in the default gateway... but it still will not work..
On all of our other machines i do not have to do anything i just plug in the
cable and everything runs fine..
