Server 2003 DHCP not saving DNS in scope.

Hello,

I have a Server 2003 acting as DHCP and DNS.  In the DHCP Manager I set the DHCP scope to save the Server as the DNS Server.  I exit DHCP manager and go back in and the setting is no longer there (all that is there is the router), I tested a couple of other scope settings and the same thing happens.  

Another odd note is that if I try to stop the DHCP service from  within the DHCP Manager I get a Message "Access is denied".  If I go to the Services Manager I can stop and start the DHCP service without an issue.

I am logged in as administrator.

I have a fairly simple setup:

Internet -> FIOS Modem -> Sonicwall (Gateway)--Switch-+-----------Server 2003 (DHCP and DNS)
                                                                                                   |
                                                                                                   +---------Win 7 workstations
                                                                                                   |
                                                                                                   +---------Win 7 workstations

The whole problem results in the workstations not getting the DNS server address.  A temp work around has been to put in a static DNS back to the server...

Any help for an odd problem would be appreciated.

Thanks,

Larry

Whenever you are getting access denied this is almost always the case where you do not have proper permissions. Are you logged in as the Local Administrator account? This would allow you to stop/start the services on this machine. However actually making administrative changes in the DHCP Management Console requires Domain Admin rights or DHCP Administrators.

Make sure that your account is part of a group that has access to make changes on the DHCP server.

I would also try rebooting the server as well to see if that makes any difference.

Hi Will,

Thanks for the feedback.  The server is also an AD and I am logged in as the administrator (administrator is in the Domain Admin group).  This was noticed right after the server was updated and rebooted the other day.

The behavior has morphed a bit.   I ran sfc /scannow last night.  After running it I can enter the DNS into the scope, exit the DHCP Manager and if I re-enter the DNS Server scope is still there.
If I try to stop the service within the DHCP Manager I still get Access Denied.   If I stop and start it from the Services Manager it works.   However after doing that and going back into the DHCP Manager the DNS scope then disappears...

I am starting to think that maybe I should uninstall the DHCP role and reinstall it, thoughts?

Thanks,
Larry

If the DHCP role is the only thing that is giving you issues regarding access denied, then removing/re-adding the role might suffice. Make sure to backup/export your scopes before you remove the role and import them back in when you add it back.

However I would also check the DHCP Event Logs as well to see if you can get more info as to what is going on.

I think that's the way to go.  I have already backed it up.

I had already checked the event logs and there were no errors or warnings on DHCP.   A few in DNS, but I think that's related to the DHCP issue/

I cannot do this until Monday when they are closed.  I'll let you know how it goes.

Thanks.

Reinstalling the role resolved the issue.   However the backup would not restore.  This was not much of an issue though, I had taken screenshots of all the settings before uninstalling and was able to recreate everything.

Thanks,

I initially suggested the reinstallation of DHCP, Will did confirm that this might be a possible solution.
