SBS 2003 DHCP Problems

Please help

I have client with SBS2003 std r2 with sp2. Today we had to replace one of our hard drives as we were alerted that
the array was degarded. I shut the server start shutdown, replaced the old drive with the new drive and rebooted. Wehn I rebooted
stated there was a DHCP error. So I went to administrative tools DHCP and sure enough the scope and the server name disappered. I added the nmanged server back to the dhcp list
and got a red x. I tried here to start the DHCP and i get the following error "system error 65535 occured" and DHCP fails to start. I have tried everything I checked permissions on the TCPIP and DHCP in Regedit everything looks normal
Before we replaced the bad drive DHCP was working fine and we had no know errors. I have tried researching and im running out of patience. any help would be greatly appreciated. I even tried running the CEICW and it immediately pops a  window and states that
ther are no DHCP server and I have define a scope. I cant even define a scope becasue it will not allow me to start dhcp. Any help would be greatly appreciated.

Thanks

Sounds like the DHCP database is corrupted. Copy the files in the DHCP folder to a temporary area then delete them. Restart DHCP and see if it comes up.
Stop DHCP server service
Rename C:\WINDOWS\system32\dhcp\dhcp.mbd to dhcp.old
Restart DHCP server service
Recreate scope, activate and authorize
Hope that helps,
Olaf

Oalf,

unfortunatley this did not work. I still receive the error. After renaming and restarting the service DHCP starts I just cannot define a scope.

Hi,

Reparing the DHCP database should work.

Refer this:

Hope this helps,

Can you please send us an ipconfig/all  of server and one workstation?

As a long shot, SBS configure DHCP using the CEICW (connect to the internet from the SBS console), try re-running it as it will often repair network issues.

I assume there is no other DHCP servers on the LAN such as a router. If so SBS will instantly detect and shut down, or not start, it's own DHCP service. Nobody enabled DHCP on the router while you were working on the server so they could maintain internet access?
RodWil,

I am aware fo the wizards with SBS2003 and CEICW, however, I cannot run this because of the DHCP issue. I get a different Error stating that no scope is defined. Which I know how to creat but the machine will not allo this to happen.


Perhaps this might help.

You may have experienced a fault in the Active directory whilst swapping drives - or at the time one of the drives failed.

In a Windows Server 2003 (or 2000) domain all DHCP servers need to be authorized in Active Directory.   So, you need to logon (or RunAs) a member of the Enterprise Admins group.  Then right click the DHCP server icon, and Authorize.

Incidentally, The RIS service also needs to be Authorized before it becomes active.

Even after you Authorize a server, each scope  must be activated individually.  So, right click the scope to activate (or deactivate).  Keep your eye on the red or green arrows to judge your success.  Note you may have to Refresh from the server icon, often pressing F5 is not enough.

Actually there is no server to right click on. If I go to Administrative tools/DHCP/xxx-winserver.xxx.local I have a red x the only options I have are Start. If I click start I get the following error: "System error 65535 occured"
Sounds like you certainly have DHCP database corruption - as Trackhappy suggested.

Any chance you have a backup that you can restore the database from?
RobWil,

There is only one DHCP server on the network and its on the server. Both their Wireless routers and their Adtran from the T1 are in Bridge mode. Someone asked me to post a copy of ipconfig/all but Im not sure how to do so on here.

thanks so far for all the help you guys have offered! at the moment DHCP is still not working
Paul we do not have a backup onsite at the moment, however, I am researching through our soffiste backups. Is there an easy way to reinstall dhcp without having to reload the server?
2. Reinstall DHCP Services on the SBS server. To do so:

a. Go to Control Panel, open Add/Remove Programs, select Add/Remove Windows
Components button.
b. Go to Network Services, click the Details button.
c. Clear the option of DHCP.
d. Click Next to uninstall the DHCP Server.
e. Delete all files in DHCP folder (%systemroot%\System32\Dhcp).
f. Open Control Panel -> Add/Remove programs, select to install DHCP
Services again.
g. Then please re-run the CEICW wizard (Configuration E-mail and Internet
Connection wizard -> Connect to the internet) to reconfigure all settings
in the wizard by NO choose the option "do not change..".
