Title: RE: [ActiveDir] DCs generating SRV records for 2 sites!?

Hi Thommes,

 

Automatic site coverage takes care that Neighbor-DCs are registering themselves into sites where no DC is. If there is a DC the DCs won’t reregister themselves for that site. You can clean up the records manually, or recommended, by enabling aging and scavenging.

 

Since you appearently moved DCs from site 1 to site 2, they are still registered for site 1 and they are registering themselves correctly for site 2. The site 1 entries will only disappear if they are deleted manually or by the scavenging process. If site 1 has no DCs registered to it other DCs will still take care of that site, since every site is supposed to have DCs. That’s what the automatic site coverage process takes care of.

 

There are good documents on this in the TechCenter, look at these:

Hi Neil/Jorge,

     The child domain DCs are generating SRV records (as seen in their local netlogon.dns and netlogon.dnb files)  for both their original site (to which they have subsequently moved back into) and the other site that they were temporarily moved to.   While I could manually remove the incorrect DNS records on my DNS server, I will just assume the child DCs will just repopulate them.  Right?  Thanks for any input!

Excuse me butting in mid thread, but if a DC was moved from site A to B, then SRV records will exist for that DC in both sites, within DNS, until old SRV records are removed thru scavenging.

 

Why not simply remove the 'incorrect' SRV records by hand, since scavenging may take a number of days to remove the old records.

 

hth,

what do you mean with "The *wrong* SRV records are being produced on the child domain DCs"?

 

questions about this...

 

* On ALL child domain DCs?

* Do you mean "the SRV RRs are in registered wrong in DNS, but the DCs itself register the correct records" or do you mean "the SRV RRs are in registered wrong in DNS, AND the DCs register incorrect SRV RRs"

Can you explain more and provide more details?

 

Jorge

Hi joe,
   I don't see where scavenging has anything to do with it.  The *wrong*
SRV records are being produced on the child domain DCs.  What I see on
my AD-integrated DNS server is just a reflection of what those DCs
register.

Sounds like you don't have scavenging enabled. Also I have seen
interesting
DNS deployments where a backup is made of the zones on a regular basis
and
the whole zone is reloaded from the backups every x hours. I won't argue
for
or against that type of system, only acknowledge that I have seen it in
the
wild...

We have a couple of child domain controllers that were moved from their
respective site into the main site using the AD Site and Services mmc.
The subnet definition was NOT changed accordingly.  This was to try to
solve
an Exchange problem (had no effect).  The DCs were moved back to their
own
original site a couple of days later.  Now I see that these DCs are
advertising SRV records for both sites!  We've tried deleting (renaming
really) the netlogon.dns and netlogon.dnb files so that they could be
generated automatically upon reboot.  The bogus site SRV records still
show
up!  Any thoughts on how we can get this back straight?  Thanks much for
any
thoughts.
