MrFrostmaul Posted October 30, 2015 Posted October 30, 2015 (edited) Hi, Currently trying to setup failover for our DHCP, but running into some issues (screenshot below) I have visited https://social.technet.microsoft.com/Forums/en-US/a60ed600-58d6-4f06-a8c5-d01104b1eaa7/server-2012-r2-dhcp-failover-error-20010?forum=winserver8gen and tried the different options mentioned, but still does not want to work. We don't have any custom options and can't figure out why it is failing. Anyone come across this? Edited October 30, 2015 by MrFrostmaul
Steve21 Posted October 30, 2015 Posted October 30, 2015 Does your 2nd DC have all the same Custom Options set? e.g. Gateway/PXE servers etc? I know you said you have none but surely you must have something set in the options? :s Steve
Steve21 Posted October 30, 2015 Posted October 30, 2015 Just a note to the above, I'm talking server options as well as Scope. The pre-defined ones for scopes still need to be the same too Steve
FN-GM Posted October 30, 2015 Posted October 30, 2015 Does your 2nd DC have all the same Custom Options set? e.g. Gateway/PXE servers etc? I know you said you have none but surely you must have something set in the options? :s Steve I had the same issue and the above was the problem. I am confident it will be this.
MrFrostmaul Posted October 30, 2015 Author Posted October 30, 2015 In the main server options under IPv4 there is nothing configured (just taken over the network and trying to straighten things out.) but under the scope options everything is configured there under that scope options, tried to create a scope on the partner server and filled out all the scope options, but when trying to replicate it won't work as it says already scope there (probably doing it wrong, so deleted it and tried again but same message.
Steve21 Posted October 30, 2015 Posted October 30, 2015 Not the IPv4 ones but the predefined One min lemme find it
Steve21 Posted October 30, 2015 Posted October 30, 2015 Oh sorry yes those ones If you look under the options and scroll down do any show delete as an option? Steve
MrFrostmaul Posted October 30, 2015 Author Posted October 30, 2015 (edited) There are none configured at that level :\ Edited October 30, 2015 by MrFrostmaul
Steve21 Posted October 30, 2015 Posted October 30, 2015 Right click on the server and go to predefined It's seperate area
Steve21 Posted October 30, 2015 Posted October 30, 2015 ^ Those are separate areas and can be defined even if it's not in the scope as above one example~ Steve
MrFrostmaul Posted October 30, 2015 Author Posted October 30, 2015 Thanks, Had a look and none are available for delete and the only one I can see that is different is 060 PXE Client which is showing as defined on the primary, but no option to add on the other servers options.
Steve21 Posted October 30, 2015 Posted October 30, 2015 (edited) If it's in one it needs to be on both or none. 060 PXE is a powershell add though. And it should show you the option to delete if it's a custom one (unless it's powershell to remove too), you sure you're looking in the options on the server and not scope? Edit - Are you actually using 060 though? As just looked and we only have 066 and 067 for PXE/WDS etc Steve Edited October 30, 2015 by Steve21
MrFrostmaul Posted October 30, 2015 Author Posted October 30, 2015 Just added it, saw the button straight after I posted. Added the option 060 into the predefined on the other server and got it setup for the failover. Thank you very much for your help and your offer
Steve21 Posted October 31, 2015 Posted October 31, 2015 Haha cool Aye one of those stupid things isn't it, think by now it would actually give you helpful errors, as it has to check what exists on both yet won't tell you what doesn't! Steve
