Cannot connect to DHCP server that just gave me an IP

Please help with bizarre issue:

XP Notebook in AD domain logs in, get IP address from Win2k3 DHCP server,
can ping and connect to anything but the DHCP server it just got an address
from. DNS shows the noteboook is properly registered. When trying the ping
the name resolves; cannot ping by IP address nor FQDN for that DHCP server.

We have given it a static address in that same class c range and it can ping
and connect to the DHCP server (which is also a print server). Went back to
DHCP and it can't ping nor connect to the DHCP server. This has happened
with three different leases. So we think it's a client issue.

We take the notebook to a differnt area and login where it gets it's IP from
a different DHCP server. All is fine. It can ping the new DHCP server and
the first DHCP server and anything else fine.

Take it back upstairs and boot up, same as before. No ping or connect to
the server that just gave it a lease! Can ping addresses above and below it
and other PC's on that class c range.

Took the PC out of the domain and put it back in. No joy. Same issues.
Ran a netsh int ip reset c:\filename.log and no joy.

Does anyone have a clue? Can't find anything specific in KB or elsewhere.

John

Hi John,

Thank you for posting!

I have some questions regarding your issue and I would like to narrow down
the cause.

1. Does the problem happen to the specific laptop only? Can other computers
which get the IP address to the DHCP server and access the DHCP server? If
so, what kind of operating system install on the computers.
2. What message it returned when you Ping the DHCP server by IP address
and/or domain name (FQDN)
3. If you specify the same static IP address as it gets from DHCP server,
will you get the same result?
4. Manually change the MAC address. If it is a motherboard build-in network
interface card, you may change it in BIOS.

Or you can try the below steps to change MAC address. This is depending on
the type of Network Interface Card (NIC) you have. If you have a card that
does not support Clone MAC address, you may not be able to change the MAC
address.

Go to Start->Settings->Control Panel and double click on Network and
Dial-up Connections.

Right click on the NIC you want to change the MAC address and click on
properties.

Under "General" tab, click on the "Configure" button

Click on "Advanced" tab

Under "Property section", you should see an item called "Network Address"
or "Locally Administered Address", click on it.

On the right side, under "Value", type in the New MAC address you want to
assign to your NIC. Usually this value is entered without the "-" between
the MAC address numbers.

Goto command prompt and type in "ipconfig /all" or "net config rdr" to
verify the changes.

If successful, reboot your systems.

I hope that the above information is helpful.

Have a nice day!

Feng,

Thank you for those suggestions and questions. We resolved this one laptop
by running WinSock XP Fix from
http://www.spychecker.com/program/winsockxpfix.html . This certainly didn't
allow us to figure out exactly what happened and exactly how to fix it but
we needed to get this PC back into production.

Regards,

John
