Delete distribution groups belongs to dead child domain name - Exchange 2010 SP1

Hi Everyone,
We just remove child domain (exchange and DC’s) and we forgot to move the distributions groups to Parent domain. (The DC’s has been force removal and clean metadata on parent DC).
Now, on parent Exchange Console those distribution lists that belongs to the demoted child domain cannot be edited/or deleted. I basically need to delete those distribution groups.
There is any way to do that? Can I use Adsiedit? If yes where can I find them?

Thanks in advance,
Criss

if it's the case (i mean only 1 DC) are you able to query the DN path of the distribution group.

dsquery group -name "DLNAME"

if you're able to do so then use ADSIedit tool to delete the DL. It will work.

Have you restarted the parent DC after performing MDC, just reboot the DC and check.

hi,

Is that distribution list name are visible in memberof tab of the user accounts. I believe it should display only the SID in the memberof Tab instead of name since the child domain is demoted.

check the logonserver name of your server in which you're able to view the distribution lists name in your exchange console.

If that logon server is a GC(global catalog) believe the metadata cleanup was not replicated to this DC. You can just uncheck the GC (means remove the GC feature from DC) then wait for 1 day once GC feature is successfully got removed, you can again enable the GC feature in the DC so that you won't see the DL name again in the exchange console.

Hi Vin,

I checked 1 user that I know is Member of one of the Distribution Groups. under his Member of TAB I can see the display name of the Distribution group like before and not SID.
When you say check the log on server name can you please explain? I have only 1 DC (GC) and 1 Exchange on the parent domain.

Regards,

I fixed the problem.
I tried to clean metadata again and this time I got this error:
DsRemoveDsDomainW error 0X2015(The directory service can perform the requested operation only on a leaf object.)
I run ntdsutil with partition management option and I deleted the naming contexts for specific child domain.
Once I did this the distribution groups has disappear from Exchange console. Next day when a new GAL has been generated the distribution groups has been cleaned.
Vin, I will give you the credits anyway. You were the only one trying to help me.

Thanks,
Criss
