We have a minor issue with our DC that starts the netlogon service
'paused' after every reboot.
Since this happens, we cannot logon to the Domain Controller as
Administrator due to "domain is not available" error.
The only way that I know of to logon is to boot up our secondary
Controller.

This happens after a power outage , etc. Our backup Controller
always
has to be on before we log on to our 'main' Domain Controller.


If our secondary controller failed, and the primary cannot log on due
to this "domain is not available" error, how would I be able to get
around this?


TIA.

Hello Tom,

If i understand you correct you have 2 DCs and if you boot the so called
secondary DC, everything is fine.

This sounds for me that you have only one DC with the DNS server role. To
connect/start the domain a DNS server MUST be available. So if the so called
primary DC is not DNS server it can not find/start the domain.

Best regards

Quoted from the other thread:
===
"Regarding any errors in the DC, none exist except for "The Active
Directory database has been restored using an unsupported restoration
procedure.
Active Directory will be unable to log on users while this condition
persists. As a result, the Net Logon service has paused. "
===

Looking it up, it's Event ID: 2103. I posted a couple of links for Tom to
read up on this error message (KB888794 & KB875495). Not sure if it was
restored with imaging software or if the AD database was manually copied at
one time or other, because he did state that specific DC's netlogon service
was set to manual and not automatic when they had to work on it in the past
for some reason.

Hope we can hear more from Tom so we can offer specific assistance.

If you don't normally have the secondary dc up, you are creating problems.
Specifically if the second dc was turned off for longer than the tombstone
lifetime. All dc's should be available all the time to participate in
replication, otherwise you can end up with lingering objects.

Just reading further on, it appears you have a seond thread on this. You
should cross post not double post.
