Strange one... Worried about my PDC

[Andy100]

Hi Guys,

I'm gonna call a tech in anyway but thought I'd have a bash here as well.

Something really strange has happened to our primary domain controller.

If I power it and the secondary domain controller down then boot the PDC back up all of the active directory is missing. It logs onto the domain when you log in but when you log into AD it says there's no domain to administer.

Now if I boot up the secondary domain controller first then boot up the PDC then everything's fine, AD is all there all my sites and services work...

I'd imagine this is because it's replicating the AD from the SDC when it boots up.

When I check the event logs there's no error messages and no trace that anything was ever wrong.


Any ideas?

That's what I can't get my head around.

It's holding all the schema roles and everything seems fine when the other one boots.

It's beyond me, time to call in a pro methinks.

Thanks J1nxy I'll give this a go tomorrow.

The more I think about it the more I think it must be a DNS problem. I guess if the local DNS was corrupt it could have this effect as it wouldn't know where to look for the roles?
