Demoted a Domain Controller but Server still authenticating to that

Demoted the domain controller DC3 last night.  But I can still see some servers are authenticating to it when I run set command.
THat DC did not have any FSMO roles, DHCP or DNS.  
Why the server still shows that and how do I point to the right DC?  I don't wand to reboot the server, it is in prodution.  I do not see any visible issues either.
Please advice.

In Active Directory Sites and Services is the server still listed here? Is it still registered as a Global Catalog server?

If the its not a DC anymore, then there is no way it can be processing any authentication requests.

That's right its still there.  Someone did not tell me truth and rescheduled to demote tonight, not last night.  Will I have to reboot servers that authenticating to that currently?  Or they will be pointed to another DCs automagically?

They will be reconfigured automatically as all requests go via DNS and once it's no longer a DC the SRV records for authentication will be removed from DNS and therefore no clients will attempt to use the old server.

The DCPROMO process requires a reboot do you will have no choice in this matter.

I mean reboot the server clients authenticated to that DC.

No.  You shouldn't need to.
