dcdiag /v query

So I created a new DC recently and demoted an old one first.

I did a dcpromo and demoted the DC fine, I also did the meta data cleanup using the GUI as its a 2008 forest/domain, just made sure all references to the old DC was removed in users and computers (as thats the only reference that was left). I forced replication across all the DCs and left it a while.

I promoted the new one and all is well. dcdiag shows no errors, readmin /showrepl shows no errors and AD Replication Status Tool shows no errors.

When I run dcdiag /v I get  invocation/latency issues as attached? My guess is that it is nothing major and to do with maybe an old DC before my time as it says Win2k DC, or possible a DC restore as that is when the invocation ID changes?

I am just curious for you AD guys out there to enlighten me as to what it is actually telling me.

You will always get the X entries in the vector were ignored. It always remembers old domain controllers when you do this command. There is no way to delete them it simply ignores them.

To elaborate..
An invocation Id is a Directory Services Database GUID that was registered on a DC.  If you ever were to restore a DB on a DC the invocation ID is updated with a new value to help ensure replication consistency and prevent USN rollback.  You can't get rid of them and have to live with them.

I would also be running netdom query dc to ensure that only DC's that are currently working are listed.

I would also recommend checking SRV recrods for any other remnat DC entries. This can be found in the _msdcs.domain.com folder under the domain.com zone for active directory. Dns Management Console is where you will find this.

OK guys thank you for the heads up.

I did the netdom query dc and it only shows the DCs that are active, the one I removed is not listed anywhere and the same goes for the SRV records.

Since there is no way to delete them so it ignores them, makes sense and explains why when you run the normal dcdiag it doesn't even mention it.

So I am happy, thank you for your time guys
