not able to connect to DHCP server

I am running windows 7, and have a win 2k3 DHCP server.  I have multiple Dell swithces in my network.  
I have roughly 65 PCs, and for some strange reason, this morning, 2 PC's can't connect to my DHCP server.  I can't ping the server, I can't browse to it.  This happened 3 weeks ago and the only way I was able to resolve it is to replace the NIC with a new one.

But that can't be the solution as everytime this occures, I just replace NICs.
When checking ipconfig, I have a good IP address, default gateway and the DHCP and DNS are both correct.
I can ping any other server on my network.

I'm puzzeled what is blocking my PC to not ping and connect to my DHCP server.
On the DHCP server, I even deleted the IP address that I had on my PC.  Then I restarted my PC and it still has the same IP. I even did a /renew and it just says "an error occured while renewing interface local area connection: unable to contact your DHCP server. Request has timed out."

Any suggestions?

Can you check the Event Viewer for further details? Try disabling Firewall, Antivirus etc(even though this shouldn't be the reason).

Also when you get this error again then try to set a static IP address on the PC. This will tell whether the PC can see the DHCP after you give it a static IP address.
Can you statically assign an IP to one of the problem machines and ping successfully?

Is DHCP Relay configured correctly on all hops on the switches if you're using different subnets?  

When you get an IP Address and are unable to ping, can you do a route print and verify that your Default route is correct?

Delete the PC's DHCP lease from the DHCP server and renew the client's IP address.  I've been running into this issue lately as well.

Try this from command prompt:


Then do

Lastly try

Let me know if you can connect to your DHCP now from the affected machines.

The flushdns and registerdns works fine.

The netsh interface ip delete (does not work)
I even tried using the actual IP address instead of IP (does not work)
error says "the following command was not found: interface ip delete

I will try the other suggestions now.

Not sure if this has anything to do with it?  I don't see anything else that can cause it.

This error occures because it can't connect to my DHCP server, which is my DC as well.

so I changed IP address to static on my PC, rebooted, I also cleared the arpcahce and it worked with static IP.  I changed it back to dynamic and it still works, I can ping my dhcp server, so that's good.

On the second PC, I did the same, but it still does not work. When static, I can ping the DHCP server, but when dynamic, I can't ping the dhcp server.  I've restared, cleared the arpcahce, removed the AV program, nothing.   The windows firewall is on by default via GP, so I can't turn that off unless I turn it off for everyone, but I know it's not the firewall as it worked fine last week and I haven't made any changes to GP.

What else can I do?  Not sure how to fix this?
It is related to your NIC. What is the state of the NIC on boot? It is either disabled or enabled. Sometimes I can't get a address too so I disable and enable the NIC and the problem is solved.
All right. Good, good, good, good for PC1.
Check the event viewer on the second machine? Is pc1s hardware identical to pc2?
Also if that is not the case see event viewer on this machine too.

Check the event viewer on the DHCP server.
Try also to reserve anIP on the DHCP server
For PC2.
DanNetwork EngineerAuthor Commented:
I already tried to disable and enable the NIC, still does not work.
I did repair, which resets the arp cache, DNS, etc... and that didn't work either.
The hardware are different on both machines.

I will check the event viewer next.
DanNetwork EngineerAuthor Commented:
Not sure what this is about, but this was on the DC server, and it was referring to my PC.
I do not see anything referring to the other, second PC.

I see this numerous times over and over again.
Did you image these two machines with the same Image clone?  Try updating the NIC driver.  I would agree that this looks like a hardware issue at this point.

(The browser (MRxSMB) error is moot since you don't have a connection to the network.  You can ignore it.)

I figured it out!!!!!!!!!!!!!!!!

In my DHCP server, I noticied there were few entries that had an explimation mark, and in the name, it had "badd_address", and it did have an IP address and MAC.
So I deleted them.

Then I went to the client, did a:
ipconfig /release

Waited a few seconds, did a ipconfig /renew and it didn't work as it couldn't connect to the DHCP server.

So I waited a few seconds and I noticied that it received connectivity, so it tried again apparently and obtained an IP address, a differrent IP address then before, as I had deleted the old address from the server when the PC was turned off.

With the new IP address, everything works fine, can ping my DHCP, and I restarted the PC just to make sure and it's still working, so that's the rest of the story.

I guess when it happens again, I need to figure out why the "bad_address" occures on my DHCP server.......
DanNetwork EngineerAuthor Commented:
LOL, exclimation mark  hmm......  this keyboard.
DanNetwork EngineerAuthor Commented:
Well, that fixed it temporarily, but the same issue has happened again, so there's something wrong with my DHCP server, as it's been 4 PCs now in 2 days.

Any advise on what I should be looking at?
