We're getting the following errors on our test domain when running
dcidag:
[WARNING] Failed to query SPN registration on DC
'pdc1.test.local'.
[WARNING] Failed to query SPN registration on DC
'pdc2.test.local'.

Any ideas on what's causing this warning?

Normally creating a reverse zone with the a PTR to all the DCs will do the
trick, because it is querying for the PTR. However you're using public IPs.
The ISP has ownership of those records and may be difficult for you to do
that. I would suggest to either try creating your own reverse for the
180.26.0.0 subnet (based on your subnet mask) or actually changing
everything over to a private subnet.

I changed everything over to a private subnet (192.168.0.0/16) and
created reverse PTR records for the DCs and I'm still getting the same
error messages.

So I am assuming you are saying that the following two records have PTRs
created for them:
'pdc1.test.local'
'pdc2.test.local'


Also, I am confused. You ran a dcdiag that you provided in your original
post for a computer called jim.test.local. Is this computer a DC?

On the computer called Jim, you have two DNS addresses listed in it's IP
properties., I assume you've changed it to the current private IP. Also, no
need to enter it twice. For DNS, once is all you need.

Please post the following information:

1. If Jim is not a DC, please run a dcdiag /v /fix on both DCs and post the
results.
2. Please run a netdiag /v /fix on both DCs and post the results as well.
3. Please provide an unedited ipconfig /all from jim, pdc1 and pdc2.
4. Please post any event log errors from the DCs (provide the EventID# and
Source)

Thanks,

Ace
