RE: [ActiveDir] Netlogon.dns (2)

[Ulf B. Simon-Weidner]

No pattern at all, sometimes kerberos SRVs, sometimes GC SRVs, sometimes SRVs which were missing in the site dns-domain but were existing in the "all-in-the-domain"-dns-domain, totally weired. Was more looking like after promotion performance issues which were preventing to write all records to the netlogon.dns, but that's a very wild guess. I would have been interested to see it after it got promoted initially, but our company wasn't involved at this point, two other companies did the migration (both of them here on the list - so I won't mention them). They were running like that for years propably - they didn't have dns aging and scavening activated so I don't think they disappeared recently.

Were the entries dropped off the end of the file, or were they missing from the middle? Any pattern to the entries that were missing?

Instead of hijacking another thread I'm going to start my own ;)

What I've seen recently and was pretty surprised: A customer of mine had incomplete netlogon.dns-files, they had some of the records which were supposed to be there but not all. On some DCs about 50% of the netlogon.dns was missing.

Really bad about this is that the tools like dcdiag only test the content of the netlogon.dns against the DNS-Service, and that the netlogon-process does not check the content of the netlogon.dns without any changes unless the file is missing. So the customer had missing DNS-Informations for ages and never noticed it - not everyone is digging around in DNS and knows what's supposed to be there ;)

DCs were W2k SP4.

Anyone seen this before? OK - I've already fixed it by renaming netlogon.dns and restarting netlogon, but I'm curious if anyone has ideas where this might come from and if anyone has seen it before.

Gruesse - Sincerely,

Ulf B. Simon-Weidner
