DHCP 003 Router dissappears after server reboot

[Guest MacMan0295@gmail.com]

I am having an issue with 003 Router dissappearing after I reboot my

Windows 2003 Server. I did some research and I thought I found the

problem to be http://support.microsoft.com/kb/936009/. Unfortunatly I

applied this patch and nothing happened. It still dissappears after

a reboot. The server is running Windows Server 2003 r2 SP2.

 

Thanks for any help

Your question is pretty vague. You mention "003 Router" as if

you are talking about DHCP (I would guess) but never mention

DHCP, whether you are using and internal or exteran DHCP

server etc.

 

If this is strictly a DHCP CLIENT issue, then you always need

to post the full, unedited, TEXT-ONLY output from "ipconfig /all".

 

Preferably you would post the one before when it worked

correctly, then the other where it was not correct....

 

Have you tried the obvious "ipconfig /refresh"?

This is a DHCP server issue. In the title I mention that it is a DHCP

issue. On the server, when configuring the Scope options, when I add

the "003 Router" option and configure it, the next time I reboot the

server it has disappeared. Please let me know if I am missing any

other information that can help figure this darn thing out. Thanks.

#This is a DHCP server issue. In the title I mention that it is a DHCP

#issue.

 

Yes, but you didn't specific "DHCP Client" or "DHCP Server" (servers

and workstations may both be such clients) and thus have wasted

a lot of time when you might have gotten a reply already.

 

#On the server, when configuring the Scope options, when I add

What happens if you close, then re-open the MMC?

 

That should save immediately -- that is a bug or something weird

is going on that is not experience by most people.

 

Do any clients actually receive the value (if you don't first reboot)?

(Perhaps the value is never getting set.)

 

Play around with activating/de-activating. Stop/start JUST the

service -- to see if the reboot is part of the problem and for

faster testing.

 

Perhaps this Google search will help:

| ~restart ]

 

First hit is this article:

After you restart the DHCP Server service, some DHCP options

disappear on a Windows Server 2003-based DHCP server

(there is a hotfix referenced)

Once I make the entry, It saves and people are able to get the value

with no problem. If the MMC closes, there is no problem there. If

you stop/start the service or reboot the server then the entry

disappears. thanks.

Check for invalid data elsewhere in the scope..

 

Check for invalid data elsewhere in the scope..

 

I had this exact same problem on one of our DHCP server scopes.

 

As I got to the point where I was going to delete and recreate the scope, I started taking note of the reservations and other scope detail.

 

I found a reservation that was set to an invalid IP address for the scope. (Scope was 172.23.3.0/24 giving range 172.23.3.1 - 172.23.3.254 and the reservation was set to 172.23.3.0 !?)

 

Once this reservation was removed, things were happy again through DHCPServer restarts.

 

I think I've seen this kind of thing before as well. Check and double check all your scope details; ranges, exclusions, reservations. Make sure they're all correct and do not break any networking rules. Sometimes Microsoft DHCP lets you put stuff in that's just plain wrong and invalid.

I had this exact same issue on one particular DHCP scope on a server I support.

 

Just as I was about to resort to deletion and recreation of the scope in question, I starting making notes of the various settings / options / reservations and found a reservation that had been set to an IP outside the range given by the scope.

 

Scope was 172.23.3.0/24

Range 172.23.3.1 -> 172.23.3.254

Reservation somehow ended up on 172.23.3.0

 

Deleted the invalid reservation, and all was happy again.

 

I think I've seen this kind of thing before with MS DHCP. Sometimes, you can put crazy settings in there that make no logical sense. When you do, it can cause other odd side-effects.

 

Check all your scope range / exclusions / reservations etc. and make sure there's no invalid data in there. It could be as simple as this.

That was exactly the issue. Thanks for the info. Soooo simple.
