Domain Controller Slow to boot (Applying Computer Settings)

Hi,

I have 2 Domain Controllers (Windows Server 2008 Enterprise) both ar
also running DNS (AD integrated).

When I boot both servers up at the same time (or boot a single server)
they stay at "Applying Computer Settings" for about 5 mins. I have rea
various things mentioning DNS client settings. If I boot 1 AD server, i
will hang at this point as well, then I boot the second AD server i
boots normally.

My DNS client settings on each server are:

AD01
Preferred DNS: 127.0.0.1
Alternate DNS: 192.168.99.32 (AD02)

AD02
Preferred DNS: 127.0.0.1
Alternate DNS: 192.168.99.31 (AD01)

Is there anything I am missing? Is this normal behavior for 2 domai
controllers? This is causing a problem with my 2008 cluster, which th
cluster name will not come online, I think this problem is related t
the slow booting of DNS/AD

Hi,

1. Use the Server IP as a preferred DNS server don?t use 127.0.0.1
2. Check your running services to disable unneeded services
3. Check the task schedule , there is a few tasks that you can disable there
that might speed your login

Hello bg_27,

This belongs to the reason that none of tthe servers can reach a DNS server
during startup. They wait until one of them has started the DNS server service
and then is aible to use it. The easiest way will be to have allways a DNS
server up and running.

Hello bg_27,

Also change the preferred DNS server to the real ip address instaed of the
loopback ip 127.0.0.1
