Very Slow DNS start on domain controller restart

Hi,

Every time I restart my domain controller, it first hangs at the following screen:

187657-image.png


After 2-4 minutes, it will finally load into the desktop. But if I click on "DNS" application, it will say the following:

187619-image.png


If I try to open group policy editor, it will not load until DNS loads.

DNS will finally load after about another 5 minutes.

In event viewer, under "DNS Server" I see this warning:


187649-image.png



I haven't had a clue why this issue is occurs yet.

Thank you

It's still waiting for replication to complete. This is the one you just promo'd right?

this is on the primary domain controller. It occurred even before I demoted and promoted my secondary domain controller again.

Ill wait for a few hours to see if it still happens and report back then.

Maybe demoting and promoting the secondary DC will fix the issue but for now its still happening.

Hi,

It's normal behavior when the first replication is not yet completed because the DNS zone is integrated DNS zone therefore it's saved in active directory.
So to load DNS zone and connect to another service depending on DNS service you have to wait to complete the first AD replication.
