Re: Domain Controller takes a long time to boot up

Thanks for your reply. I have attached the ipconfig of both DC's below.

Please note that the computer room was totally shutdown, which means
that at powerup, no other DC/DNS is available. Both were booting up!

Another user posted his reply with the following links:

IPCONFIG output: Note that the default gateway is our ISA Server
which is still down at the time the DC's are booting up.

Hello.

We had to shutdown servers in our computer room last
night due to high temp. The AC condenser froze.

After the AC was back to normal, I started the DC's first.
DC1 took a long time to boot up. It stayed long on the
"Preparing network connections" then on the next one
I couldn't remember. So I started up the DC2. That
took a long time to boot up too.

What do I need to know to speed up the bootup of
Domain Controllers with Active Directory?

Thanks in advance.

DNS can have alot to do with it, but can't say for sure without knowing
your config. What DNS servers are configureed in the DC's IP properties?

If you have one of the replica DCs in the Site as the first entry and
itself as the second entry, I can see why when booting both DCs up at the
same time they can't find their DNS server, even if it is itself, because
it goes through the DNS resolver resolution process time-out before it
goes to the second one to find the DC, which even if itself.

If you have itself listed first, then a replica DC in the same subnet as
it's second one it will boot quicker.

If you have your ISP's listed in the config, it will be problematic
because the cardinal rule is to not use your ISP anywhere other than a
forwarder.

If you can post an unedited ipconfig /all of both DCs, it will be
extremely helpful towards a diagnosis.

Thanks,
